"A volleyball court is 30.0 ft. wide and 60.0 ft. long, with the net in the center of the court. Lines on the floor of the court mark the court boundaries. A volleyball player, standing 12.0 ft. from the net on her side, hits the volleyball over the net. She hits the ball from a height of 7.80 ft., and 2.10 seconds later, it lands on the back line on the other side, scoring a point for her team. Air resistance is negligible.
A) What is the magnitude of the velocity of the ball when she hits it?
B) What direction is this velocity vector pointed in?
C) What is the magnitude of the velocity of the ball when it hits the floor?
D)what direction is the velocity vector (in part C) pointed in?"
