|A rocket is fired at a speed of 75.0 m/s from ground level, at
an angle of 60.0° above the horizontal. The rocket is fired toward an
11.0-m-high wall, which is located 27.0 m away. The rocket attains its
launch speed in a negligibly short period of time, after which its engines
shut down and the rocket coasts. By how much does the rocket clear the
top of the wall?
