A rocket is fired at a speed of 82.0 m/s from ground level, at an angle of 31.0 ° above the horizontal. The rocket is fired toward an 6.95-m high wall, which is located 18.0 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?
