Question

I punt a soccer ball and it rolls up a hill to my partner. The soccer ball has a 11 cm radius, and a mass of 425 g.

a) Soccer ball has a moment of inertia of I = 9/10mR² . Calculate the moment of inertia

B) How much initial speed should the ball have to make sure that it reaches my partner, at the top of a h = 20 m tall hill?

thanks.

A solid, uniform ball rolls without slipping up a hill. At the top of the hill, it is moving horizontally; then it goes over the vertical cliff. Take V = 25.0 m/s and H = 30.0 m . Part A: How far from the foot of the cliff does the ball land? Part B: How fast is it moving just before it lands? Part C: Notice that when the ball lands, it has a larger translational speed than it had...
