(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

During a baseball game, a batter hits a pop-

up to a fielder 86 m away.

The acceleration of gravity is 9.8 m/s2 .

If the ball remains in the air for 6.3 s, how

high does it rise? Answer in units of m.

2. Relevant equations

y=vi(sin theta)t-1/2g(t)^2

3. The attempt at a solution

I'm not even sure I went about this right...I was only able to fill in that equation this much:

y=vi (sin90)6.3-1/2(-9.8?)(6.3)^2

As you can see, I'm pretty clueless as to how to find the height of the ball at it's highest point...
