A softball is hit over a third baseman's head with some speed v0v0v_0 at an angle theta above the horizontal. Immediately after the ball is hit, the third baseman turns around and begins to run at a constant velocity V=7.00m/sV=7.00m/s. He catches the ball t=2.00st=2.00s later at the same height at which it left the bat. The third baseman was originally standing L=18.0mL=18.0m from the location at which the ball was hit.

a) Find v0v0v_0. Use g=9.81m/s2g=9.81m/s2 for the magnitude of the acceleration due to gravity.

b) Find the angle theta in degrees.
