Question 1: Paige is the tallest player on South's Varsity volleyball team. She is in spiking position when Julia gives her the perfect set. The 0.223-kg volleyball is 2.32 meters above the ground and has a speed of 1.34 m/s. Paige spikes the ball, doing 9.68 Joules of work on it.

Determine the speed of the ball upon hitting the floor on the opponent's side of the net.

Question 2: In April of 1976, Chicago Cub slugger Dave Kingman hit a home run which cleared the Wrigley Field fence and hit a house located 530 feet (162 m) from home plate.

Determine the speed of the ball as it passed above the wall.
