Asoftball is hit over a third baseman's head with some speed v0 at an angle θ 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/s. he catches the ball t=2.00s later at the same height at which it left the bat. the third baseman was originally standing l=18.0m from the location at which the ball was hit.

a) find v0. use g=9.81m/s2 for the magnitude of the acceleration due to gravity.

express the initial speed numerically in units of meters per second to three significant figures.

b) find the angle θ in degrees.

express your answer numerically in degrees to three significant figures.
