Leilani Mitchell of the Washington Mystics is 5 ft 5 inches and when she makes a free throw the ball leaves her hand about h = 2 m above the ground. The center of the hoop is r = 4.3 m away in the horizontal direction and y = 3.1 m above the ground. Treat the ball as a point particle (ignore the radius of the ball) and neglect air resistance. (A) If the ball takes t = 0.7 seconds to go from her hand to the hoop, find the magnitude and direction of the velocity with which it leaves her hand.
(B) Find the magnitude and direction of the velocity of the ball as it goes through the hoop.
