**1. Homework Statement**

The data is taken from a graph. The initial velocity is 31m/s. I found the horizontal velocity to be 21m/s. The time the ball travels is 5 seconds. The total distance the ball travelled is 105m. The ball lands at the same vertical level at which it starts. Air resistance can be neglected.

**2. Homework Equations**

Im pretty sure I have to use this equation, where t= 2.5.

v = v(initial) + at

I used the pythagoreum theorem to find the initial vertical velocity to be 22.8m/s. Then divided it by 2.5. What I came up with, -9.12, which is wrong.

I just cant find the acceleration due to gravity. It looks straight forward but I am missing a step. Any ideas?

Thanks!
