A catapult of pole length 9r throws a watermelon from one end of a pole which rotates about an axis at the other end with angular speed w.
A smaller catapult of pole length r throws another watermelon from one end of a pole
which rotates about an axis at the other end with the same angular speed was the first
catapult.
How does the linear speed of the larger catapult's watermelon Ularge compare with
the smaller catapult's watermelon Usmall ?
