Here's a problem that I just can't seem to get. I just need to get started out.(adsbygoogle = window.adsbygoogle || []).push({});

A placekicker is about to kick a field goal. The ball is 26.9 m from the goalpost. The ball is kicked w/ a initial velocity of 19.8 m/s at an angle theta above the ground. Between what two angles, theta1 & theta2, will the ball clear the 2.74-m-high crossbar?

What am I looking for here? Do I even get the question?

This is my interpretation: What is the angle of intersection if I draw a horizontal line 2.74-m-high off the ground to the path of the ball? I'm guessing I'm going to have to use Vnaught*cos(theta). Is that what I'm supposed to figure out? If that is, how (just nudge me in the right direction)?
