A rocket is fired at a speed of 79.0 m/s from ground level, at an angle of 47.0 ° above the horizontal. The rocket is fired toward an 11.3-m high wall, which is located 16.0 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?
A rocket is fired at a speed of 63.0 m/s from ground level, at an angle of 51.0 ° above the horizontal. The rocket is fired toward an 20.8-m high wall, which is located 20.0 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?
A rocket is fired at a speed of 71.0 m/s from ground level, at an angle of 33.0 ° above the horizontal. The rocket is fired toward an 16.2-m high wall, which is located 31.0 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?
A rocket is fired at a speed of 78.0 m/s from ground level, at an angle of 34.0 ° above the horizontal. The rocket is fired toward an 13.1-m high wall, which is located 28.0 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?
A rocket is fired at a speed of 74.0 m/s from ground level, at an angle of 46.0 ° above the horizontal. The rocket is fired toward an 13.4-m high wall, which is located 24.0 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? (Write on paper)
A rocket is fired at a speed of 71.4 m/s from ground level, at an angle of 60.9° above the horizontal. The rocket is fired toward an 10.4 m high wall, which is located 29.5 m away. By how much does the rocket clear the top of the wall?

Chapter 03, Problem 38 Multiple-Concept Example 4 deals with a situation similar to that presented here. A marble is thrown horizontally with a speed of 21.7 m/s from the top of a building. When it strikes the ground, the marble has a velocity that makes an angle of 42° with the horizontal. From what height above the ground was the marble thrown? Number the tolerance is +/-2% Units
A marble is thrown horizontally with a speed of 10.2 m/s from the top of a building. When it strikes the ground, the marble has a velocity that makes an angle of 76 ° with the horizontal. From what height above the ground was the marble thrown?
A projectile is fired from level ground with an initial speed of 24.3 m/s at a launch angle of 32 degrees relative to the horizontal direction. Where does the projectile land if you ignore air resistance? (Assume 3 significant digits).^ (2)
