Homework Statement
A ball with mass, m is released from rest at a height, h1 and is allowed to roll down a ramp. After wrapping around a loop, it rolls up an incline of angle theta to height, h2, from which it launches. We measure the horizontal distance, d, it travels. To investigate the relative effect of friction, find the ratio of the work done by friction, Wf, to the work done by gravity, Wg.
The parameter is set to
m=85 [g], h1=1.00 [m], h2=0.53 [m], theta=45 degrees
The measurement is d= 30 [cm]
The ratio of work done by friction to work done by gravity is
Wf/Wg= ? (This is what I'm looking for)
Is this larger or smaller than you expected?
