As we know:** V**^{2}** - V**_{0}^{2}** = 2(-g) (Y)** , Y is distance between V and V_{0 }, The sign of g is negative because when baseball goes up, its speed decreases.

At maximum height, velocity is zero (V = 0).

**-V**_{0}^{2}** = 2(- g) H** **→** **Y**_{max}** = H = V**_{0}^{2}** / 2g → H = (12.1)**^{2}** / (2*9.80) → H = 7.5 m**

Wow, thank you!2d

How would we find at what times the ball passes through half the maximum height? Time is never given, is it?3d
