## Homework Statement

A ball is batted with a velocity of 30 m/s at an angle of 30 degrees above the horizontal from a height of 1.0 m above the ground. Will the ball clear a 2.5 m high fence which is 30 m away? By how much will it miss or clear?

## Homework Equations

ballistic path equation? delta y = (-gx^2/(2v)^2*(cos @)^2) + [email protected]

@ = angle

## The Attempt at a Solution

I used the ballistic path equation, and set the delta y = 1.5. On the other side i plugged in the 30 for x, 30 degrees for @, and vi as 30m/s.

I got clear by 12.5m, but I don't think that is right.
