A solid, uniform ball of mass 16.9 kg and radius 0.35 m, rolls without slipping up a hill of height 16.5 m, as shown in the figure. At the bottom of the hill the ball has a velocity of 26.1 m/s. At the top of the hill, it is moving horizontally, and then it goes over the vertical cliff.
1) What is the total initial kinetic energy of the ball at the bottom of the hill? (Use the numbers in the introduction, not the picture.)
2) What is the velocity of the ball just as it leaves the top of the hill?
3) How long is the ball in the air?
4) How far from the foot of the hill does the ball land?
%0 How fast is it moving just before it lands?
