Question

A rugby player runswith the ball directly toward his opponent's goal, along thepositive direction of an x axis. He can legally pass the ball to ateammate as long as the ball's velocity relative to the field doesnot have a positive x component. Suppose the player runs at speed4.0m/s relative to the field while he passes the ball with velocityvBP relative to himself. If vBP has magnitude6.0 m/s, what is the smallest angle it can have for the pass to belegal?

Explanation / Answer

Vx=4m/s Vy=6m/s Vy/Vx=tan =tan^-1(6/4)=56.3
