Example Problems

Problem 1
A golf ball rolls off a horizontal cliff with an initial speed of 11.4 m/s. The ball falls a vertical distance of 15.5 m into a lake below. (a) How much time does the ball spend in the air? (b) How far from the edge of the cliff does the ball land? (c) What is the speed v of the ball just before it strikes the water? (Solutions)

Problem2
A rocket is fired at a speed of 75.0 m/s from ground level, at an angle of 60.0o above the horizontal. The rocket is fired toward an 11.0 m high wall, which is located 27.0 m away. By how much does the rocket clear the top of the wall? (Solutions)
