This applet shows the results of releasing a frictionless blockand a rolling disk with equal masses from the top of identicalinclined planes.

This applet shows the same situation, but it also shows, throughbar graphs that change with time, the way that the energy istransformed as the box and the disk go down the inclined plane.

Assume that the box and disk each have mass m , the topof the incline is at height h , and the angle between theincline and the ground is ? (i.e., the incline is at anangle ? above the horizontal). Also, let the radius of thedisk be R

How much sooner does the box reach the bottom of the inclinethan the disk?Express your answer in terms of some or all of thevariables m , h , ? , and R ,as well as the acceleration due to gravity g.
