Frictionless Definition and 468 Threads

not even sure where to start on this one Consider the following frictionless collision: Mass A (60 kg) moves west at 5.00 m/s and mass B (20 kg) moves south at 20 m/s. They collide and stick together. 1.) what are the magnitude and the direction of their velocity after they stick together...

I tried working this problem- but it doesn't come out right.. any help? My answers are in blue. :cry: --- A child holds a sled on a frictionless, snowcovered hill, inclinded at an angle of 27 degrees. 1) If the sled weights 60 N, find the force exerted on the rope by the child. Answer...

A block is given an initial velocity of 3.00 m/s up a frictionless 22.0° incline. How far up the incline does the block slide before coming (momentarily) to rest? So basically, how far does it go up before the block starts falling. http://img11.paintedover.com/uploads/11/p522.gif At first...

Hi, I am trying to finish my homework and I can't figure out one problem. Can you help me, please? A block (mass m1) lying on a frictionless inclined plane is connected to a mass m2 by a massless cord passing over a pulley. a) Determine a formula for acceleration of the system of the...

Is there anything such as a frictionless surface? Why?

hi, I am having a little trouble with the last part of this problem. A particle of mass m is moving on a frictionless horizontal table and is attached to a massless string, whose other end passes through a hole in the table, where i am holding it. Initially the particle is moving in a...

This is the question that i have on my paper... Two discs (both circular shape) on a frictionless table, disc 1 with mass 100g moves with velocity 1m/s and collides "head on" elastically without any energy loss with disc 2 with mass 200g and motionless; what will be the final velocity after...

A 2.0-kg body rests on a frictionless wedge that has an inclination of 65.0° and an acceleration a to the right such that the mass remains stationary relative to the wedge. Find a This is one of the question i had to do for HW. Not really asking for an answer but it would be great if you...

A pendulum (clock) is moderately nonlinear for small angles of displacement. Is simple harmonic motion better approached by introducing a degree of friction into its works?

there is an object suspended on a frictionless inclined plane by a rope parallel to the incline. (the tension in the rope is 5000N). The angle on the incline is 25. I need help to find the weight of the object, I've tried everything! Thanks.

A massless, frictionless pulley is suspended from a rigid rod. Two masses, m (50 kg) and M (60 kg), are suspended on either side of the pulley, respectively, by a light, inextendable cord. Determine the accelerations of the masses. I drew the force diagrams of both; there is an upward...

I just have a question about cylinder. If a cylinder is on a frictionless inclined plane, does it spin as it comes down? I guess on a level surface, frictional force is required for a cylinder to roll, but I'm not sure about inclined plane.

does anyone know how frictionless environments affect the acceleration and the universal constant? Please help!

QUESTION If it were possible to make a tough, heat resistant and truly frictionless substance, what applications would it have? [?]

Is there any such thing as a frictionless surface?

If you place a radiometer in a frictionless enviroment and eliminate mechanical failure how fast will it spin? Since the frequency of c is very high, the doppler shift of light reaching the white and black side is virtually negilable, even if the radiometer is spinning at high speeds,this...

[SOLVED] Frictionless Environment K...heres a question for you people out there...I am totally lost and can't seem to figure this out. I've been trying for about 2 weeks now and still can't figure it out...maybe someone in here can help me You are standing on the edge of a frozen pond where...

A frictionless system consists of a swing of given length and its massive rider, initially at rest. Is it possible for the rider to kick this system into its unforced natural frequency?
