Kicking a football 36m from the goal, which is 3.05m high. The ball leaves the ground with a speed of 20m/s at an angle of 53 degrees to the horizontal. By how much does the ball clear or fall short of clearing the crossbar?(adsbygoogle = window.adsbygoogle || []).push({});

delta y = v_{0}cos(theta)delta t

The thing is, I don't know delta t, and the equation for delta t I have is delta t = delta x/ v_{0}cos(theta), but the only way of knowing delta x also requires delta t...

Can someone please walk me through the problem? (I can do the math myself but just what equations to use and such.) thanks a lot!
