The football player at A throws the ball in the y–z plane at a speed v_A = 50 ft/s and an angle θ_A = 60° with the horizontal. At the instant the ball is thrown, the player is at B and is running with constant speed along the line BC in order to catch it. Determine this speed, v_B, so that he makes the catch at the same elevation from which the ball was thrown.
