Question

A bowling ball (mass=7kg, radius=0.15 m) rolls up a ramp with a 0.8 m vertical rise. Ignore frictional losses and assume that the mass of the ball is distributed uniformly. The translational speed of the ball is 6 m/s at the bottom of the ramp. (Isphere=(2/5)MR^2)

At the bottom of the ramp, what is the

1.) moment of inertia

2.) linear speed

3.) angular speed

4.) translational KE

5.) rotational KE

6.) gravitational PE

Use this information and the conservation of energy relation to determine the speed of the ball at the top of the ramp.
