73. At t = 0, the baseball player hits the ball with an initial velocity of 32 m/s and an angle of 55° with the horizontal range. A player 85 m from the hitter shoots at t = 0 and the line joining them makes a 22° angle with the ball's release line (see Figure 3-50) to catch the ball. What speed and direction must this player move to catch the ball at its same level of release?
