A solid ball (sphere) rolls without slipping along a horizontal surface, then down a ramp and then along a lower horizon

Post by answerhappygod »

A solid ball (sphere) rolls without slipping along a horizontal surface, then down a ramp and then along a lower horizontal surface. The ball's translational velocity (of the center of gravity) changes from u1 = 2.70 m/s to u2 = 3.70 m/s. What is the height, h, of the ramp?
HINTS: The height of the center of gravity of the ball changes by a height equal to the height of the ramp. Refer to Knight's MoI Table for the moment of inertia of a solid sphere. As you work the problem, you will see that you do not need to know the mass or the radius of the ball.
