Homework Help: Physics

Posted by AfterLife on Friday, July 22, 2011 at 12:12pm.

Derive a function that gives the final speed of the cart as a function of the masses, ramp angle and distance up the ramp that the cart moves. Use conservation of energy to do this-no kinematics or Newton's Laws.

I have 3 trials ,, 3 angles and 3 masses ( cart moving up the ramp ) and weights haging down a rope that passes through a pully.

I can't use this equation V = sqr 2gh ,, because then all of the final velocities of the 3 trials are equal.
