A softball is hit over a third baseman's head with some speed vo 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$=7\mathrm{.}00$m$/$s$.$ He catches the ball t$=2\mathrm{.}00$s later at the same height at which it left the bat. The third baseman was originally standing L$=18\mathrm{.}0$m from the location at which the ball was hit. Find v$0.$ Use g$=9\mathrm{.}81$m$/$s$^2$ for the magnitude of the acceleration due to gravity.
