1. The problem statement, all variables and given/known data
A softball is hit over a third baseman's head with some speed (unknown) at an angle (unknown) above the horizontal. Immediately after the ball is hit, the third baseman turns around and begins to run at a constant velocity 7m/s . He catches the ball 2.0s later at the same height at which it left the bat. The third baseman was originally standing 18 from the location at which the ball was hit.

2. Relevant equations

Find the initial Vo. Use 9.8m/s^2 for the magnitude of the acceleration due to gravity.

Find the angle (unknown) in degrees.

3. The attempt at a solution

im just not sure on how or where to start with this one... any help or point in the right direction would be helpful. My bigest problem is i dont know what to put where... i can do the math i just dont know what is what... thanks

This is a projectile problem. Don't you have any relevant equations to use for projectile motion? Hint: take a look at the 1st item in my footer.
