James realizes that he can try to get Kevin by having two balls roll down from opposite hills. Ball one is 15kg and is being rolled down a hill of height 32m, ball two is 20kg, and is rolling down in the opposite direction from a height of 18.5m. What are their final velocities at the bottom of the hill? If they are now on a flat plane and collide in a completely elastic collision, what are their final speeds after the collision?

It is a sunny day, and we have decided to do lab outside instead of staying cooped up. Ceylani goes to the top of Jordan Hall, and throws a ball of mass 4.87 kg down from the top of Jordan which is 124 m tall. Her lab partner, Tray, is waiting at the bottom to collect the ball and return it, for more data trials. The ball has a speed of 3.8 m/s when Ceylani throws it straight down. What is the speed of the ball as it reaches the ground? Your Answer: units Answer
