Dynamics V1 1. A ball moves horizontally with an initial velocity V1, as shown above. It is then struck by a tennis racket. After leaving the racket, the ball moves vertically with a velocity V2, which is smaller in magnitude than V1. Which of the following vectors best represents the direction of the average force that the stick exerts on the ball? (A) 4 (n) \\ m m, \\ (E) /
