How can you calculate kinetic energy?

Ball 1 is thrown into the air and it follows the trajectory for projectile motion shown in the drawing. at the instant it is at the top of its trajectory, ball 2 is dropped from rest at the same height.

A 2.9 kg ball strikes a wall with a velocity of 8.6 m/s to the left. The ball bounces off with a velocity of 7.3 m/s to the right. If the ball is in contact with the wall for 0.
