    So you have the correct parametric, you just need h=2.5 in the second equation. You should then plot it to answer the other equations. The final equation will be (x,y) but sub your parametric equations for x and y.

    Here's your plot - http://www.wolframalpha.com/input/?i=parametric+%28136*cos%2829%29+*+t%2C136*sin%2829%29+*+t-16t%5E2%2B2.5%29

    What is the maximum value of x that you see there? Is it greater than 415? If so, he hits a homerun.

    $$ Path=(136*\cos(29) * t,136*\sin(29) * t-16t^2+2.5) $$ Just multiply everything and leave "t" alone, that's your rectangular coordinate.
