In a football game the defender is running to intercept the receiver. It is given that this is a kinematics problem in which both players are experiencing uniform motion. The receiver is running at 7 m/s. The blue and green dots represent the initial positions of the players. The angle ? represents the running trajectory of the defender, as shown, and s is the initial distance between the two players. At what velocity must the defender run at in order to intercept the receiver, as shown in the figure below? What is the distance traveled by the receiver (d1) and the defender (d2)? (
