But what about the about the change in potential energy as the arm swings upward?

Homework Statement Homework Equations Conservation of liner and angular momentum H1=H2 r x M1V1= r x M2V2 G1=G2 M1V1=M2V2 The Attempt at a Solution I've gotten an equation for the velocity of the block and clay after the impact, and I also know that when the block reaches the highest point...

Homework Statement A block of 1kg is resting on an incline of 20° that has a coefficient of friction μk=0.45 with the surface. It is connected with a mass less string to a friction-less pulley of mass 0.10 kg to a hanging block of 2 kg. What is the acceleration of the system without ignoring...

I got it, thank you!

Homework Statement [/B] A shperical shell of mass = 1kg and radius 2.0cm is released from rest at the top of an inclined plane at a height of 1.00m. The ball rolls down the incline without slipping, what is the velocity of the center of mass at the bottom of the incline.Homework Equations I'm...

How does this look?

The assumption that the accelerations are constant is what gets me. Wouldn't the accelerations at each point be dependent on the velocity of the opposite component at that point? So the Acceleration of x depends on the velocity of Y, and vice versa, and then those accelerations give the next...

We were told to only take two forces into account, Magnus, and the force of gravity. The ball is spinning about the axis coming out of the paper if you were to be looking down on to it.

Upon more research it seems we should be trying to solve these as 2 coupled 2nd order ODE's, which we can bring down into 4 first order ODE's and use Runge-Kutta on, but that is where I'm stumped.

Yes sorry, the accelerations are not constant in time, but are depending on the opposite velocity from the step before hand.

Hi there, so for my Differential equations class we are trying to model the vertical displacement of a curveball that is only in 2 dimensions, the X-Y plane, with Y being the vertical displacement, and X being the horizontal displacement. To do this we were told that the 2 forces acting on the...

I don't know. As long as someone agrees with this, I'll talk to my teacher.

Homework Statement We have 6 lightbulbs that are identical attached to a battery, and we need to list them from brightest to dimmest. This is what they look like. Homework Equations None...? The Attempt at a Solution So, my thinking is that bulbs 6,1,2 are the brightest and the same...

Well outside the shell we know that we can treat it like a point charge, but we are withing the material of shell. I know what the formula for an E field inside of an solid sphereical insulator is, but does it change because now the insulator is a shell?

Homework Statement We are asked to calculate the electric field inside of the a spherical insulating shell with an inner radius of 10cm and an outer radius of 20 cm and a charge density of 80 uC/M^3. Additionally, a +8uC charge is added to the center of the shell.Homework Equations Gauss's...
