1. A rock is thrown horizontally at m/s from the top of a cliff m high. How many seconds does the rock take to reach the ground?

2. What is the horizontal displacement (in m) of the rock in the previous question?

3. A ball is thrown from the top of a building with a horizontal velocity of m/s, and lands m away from the base of the building. How high (in m) is the building?

4. A gun shoots a bullet at m/s at an angle of º above the horizontal. The bullet embeds into a tree at the same height as it left the muzzle. Neglecting air resistance, determine the bullet's time of flight in seconds.

5. Determine the bullet's horizontal displacement, or "range," (in km) in the previous question.
