Inelastic collision Definition and 330 Threads

almost there-inelastic collision at an angle Two cars, both of mass m, collide and stick together. Prior to the collision, one car had been traveling north at speed 2v, while the second was traveling at speed v at an angle phi south of east. After the collision, the two-car system travels at...

After a completely inelastic collision, two objects of the same mass and same initial speed move away together at half of their initial speed. (a) Find the angle between the initial velocities of the objects ∑pxi = mvi ∑pxf = 2mvfcosӨ mvi = 2mfvcosӨ ∑pyi= mvi ∑pyf = 2mvfsinӨ...

You might or might not have seen the astro blaster. But if you drop two soccer balls (stacked together) you'll notice that the smaller top soccer ball lifts up to great heights. I am researching this phenomenon for my extended essay and would really appreciate it if you guys could provide me...

*** Elastic and Inelastic Collision explanation *** 1) Why energy and momentum are conserved in elastic collision? 2) Why only momentum is conserved in inelastic collision? Why energy is not conserved? Answers: Conservation of momentum is a consequence of Newton's third law. From the...

here is how it goes, A block of mass m_1 = 2.0kg slides along a frictionless table with a speed of 10m/s. Directly in front of it, and moving in the same direction, is a block of mass m_2 = 5.0kg moving at 3.0m/s. A massless spring with a spring constant k=1120N/m is attached to the backside of...

Say we have 2 particles moving in the same direction, which undergo an elastic collision. Take the rest mass of particle to be m_1, the rest mass of particle 2 to be m_2, with velocities u_1,u_2, with u_1>u_2. Assume they collidie inelastically to form a new particle m3 Are my conservation...

Can anyone help me with this? A steel wrecking ball of mass 200kg is fastned to a 10m long chain which is fixed at the far end to a crane. The ball is released when the chain is horizontal. At the bottom of the path the ball strikes a 1000kg car initally at rest on a frictionless surface. The...

a ball is dropped from rest at the top of a 6.10m-tall building, falls straight downward, collides inelastically with the ground, and bounces back. the ball loses 10.0% of its kinetic energy every time it collides with the ground. how many bounces can the ball make and still reach a window sill...

a block of mass m1 = 2kg slides along a frictionless table with a speed of 10m/s. Directly in front of it, and moving in the same direction is a block of mass m2 = 5kg moving at 3.0m/s. A massless spring with a spring constant of k = 1120N/m is attached to the near side of m2. When the blocks...

I've been working on this problem for a long time now, and my answer's off by about 0.1 m. I've looked at the problem several times, and I can't figure out why my answer's off. I would appreciate any help. Here's the problem, and my work. "A 0.2 kg frame, when suspended from a coil spring, is...

Okay in an inelastic collision the formula the book taught me to use is this one: m1v1 + m2v2 = (m1 + m2)V' Now I've done every single problem in the book including the extra exercises, but of course when it comes to doing the homework they have to ask you questions which they haven't taught...

Question A rifle bullet with mass 8.00 g strikes and embeds itself in a block with mass 0.992 kg that rests on a frictionless, horizontal surface and is attached to a coil spring. The impact compresses the spring 15.0 cm. Calibration of the spring shows that a force of 0.750 N is required to...

Please help. Two particles move perpendicular to each other until they collide. View Figure Particle 1 has mass m and momentum of magnitude 2p, and particle 2 has mass 2m and momentum of magnitude p. Note: Magnitudes are not drawn to scale in any of the figures. a. Suppose that after the...

After a completely inelastic collision between two objects of equal mass, each having initial speed, v, the two move off with speed v/5.5. What was the angle between their initial directions? Well, inelastic collision so it looks like I'll be using the momentum equation in here. My professor...

Can anyone help me with theses problems? 1. A 500 g cart is released from rest 1.0 m from the bottom of a frictionless, 30 ramp. The cart rolls down the ramp and bounces off a rubber block at the bottom. The figure shows the force during the collision. After the cart bounces, how far does...

This is probably easy for most people, but I can't quiet seem to understand it. Two automobiles have a perfectly inelastic collision. The automobiles, which are identical models except for the color and which contain only drivers of identical masses, meet at an intersection. Each was moving...

Hi, I have the following question to solve, and whilst I've got ideas I have no idea if there right: Do we use F=ma ? Thanks Graham

A 16 g bullet strikes and becomes embedded in a 1.30 kg block of wood placed on a horizontal surface just in front of the gun. If the coefficient of kinetic friction between the block and the surface is 0.22, and the impact drives the block a distance of 8.5 m before it comes to rest, what was...

This problem's got me stumped. "After a completely inelastic collision between two objects of equal mass, each having initial speed v, the two move off together with speed v/3. What was the angle between their initial directions?" Any help would be appreciated!

I forget how to solve one dimensional motion problems with friction, which is holding me up in this problem: a 5.00 g bullet is fired horizontally into a 1.2 kg wooden block resting on a horizontal surface. The coefficient of kinetic friction between the block and surface is .2. The bullet...

Hi everyone. I need some help with the following question. In a traffic accident, a car of mass 2000kg traveling south collided in the middle of an intersection with a truck of mass 7000kg traveling west. The vehicles locked and skidded off the road long a line pointing southwest. A witness...

Problem: A thin rod of mass M and length L rests on a frictionless table and is struck at a point L/4 from its center of mass by a clay ball of mass m moving at a speed v (the velocity vector is perpendicular to the rod). The ball sticks to the rod. Determine the translational and rotational...

Yet another problem I'm breaking my head with: A thin rod of mass M and length L is suspended vertically from a frictionless pivot at its upper end. A mass m of putty traveling horizontally with a speed v strikes the rod at its center of mass and sticks there. How high does the bottom of the rod...

Two identical balls made of putty, each of mass 1.50 kg, are suspended from strings of length 28.0 cm so that they touch when in their equilibrium position. We pull one of the balls back until its string makes an angle theta = 73.0 degrees with the vertical and let it go. It collides totally...

Hello, This concerns a collision between two spherical balls of equal mass and radius. The collision is two dimensional and not completely elastic. The secondary ball begins stationary. The primary ball travels along the horizontal axis with a given velocity. After the collision, the...

A car weighing 900 kg is waiting at a stop sign. A car weighing 1200 kg hits the oter car. The cars move .76 m after the collision. The coefficient of friction between the sliding tires and the pavement is .92. I need to find the speed of the car right before the collision. I don't know what...

I already posted this in the General room, so sorry. It should have been in here in the first place. Here's a question for anyone out there who would really like to less-than-moderately challenge their physics skills: There is a 40 kilogram box hanging from the ceiling, at rest. A bullet with...

Here's a question for anyone out there who would really like to less than moderately challenge their physics skills: There is a 40 kilogram box hanging from the ceiling, at rest. A bullet with a mass of 0.01 kilogram hits it, forcing it to swing back on the ropes. As it swings back, it gets...
