A football player catches a pass and runs down the sideline at vp = 6.0 m/s. A defending player directly across on the other sideline runs to intercept. If the defending player runs at vd = 9.0 m/s in a straight line, at what angle relative to the sideline should they run to intercept the player? Quiz Kinematics in Two Dimensions Problem 2.png
