A solid uniform ball of mass 143 kg and radius 021m rolls, Ask an Expert

Academics

A solid, uniform ball of mass 14.3 kg , and radius 0.21m , rolls without slipping up a hill of height 29.4m , as shown in the figure . At the bottom of the hill the ball has a velocity of 33.4 m/s. At the top of the hill, it is moving horizontally, and then it goes over the vertical cliff.

What is the total initial kinetic energy of the ball at the botton of the hill? Don't forget to use the numbers in the introduction not the picture.

What is the velocity of the ball just as it leaves the top of the hill?

How long is the ball in the air?

How far from the foot of the cliff does the ball land?

How fast is it moving just before it lands?
