The rock has a height <em>y</em> at time <em>t</em> according to
<em>y</em> = 25 m + (60 m/s) sin(32°) <em>t</em> - 1/2 <em>gt</em> ²
where <em>g</em> = 9.8 m/s² is the magnitude of the acceleration due to gravity.
Solve for <em>t</em> when <em>y</em> = 0. The quickest way to do this is with the quadratic formula.
0 = 25 m + (60 m/s) sin(32°) <em>t</em> - 1/2 <em>gt</em> ²
<em>t</em> = (-(60 m/s) sin(32°) + √[(60 m/s)² sin²(32°) - 4 (25 m) (-1/2 <em>gt</em> ²)]) / 2
(ignoring the negative root because that would make <em>t</em> negative)
or approximately
<em>t</em> ≈ 7.2 s
