This video tutorial provides plenty of examples and practice problems on projectile motion for students taking regular physics in preparation for an upcoming test or exam.
Here is a list of problems in this video:
1. A rock is dropped from the edge of a 765 meter cliff. How long does it take to hit the ground?
2. A stone is dropped from a building and takes 4.3 seconds to hit the ground. How tall is the building?
3. A monkey throws a banana horizontally at 14 m/s from the top of a tree. The banana hits the ground 3.1 seconds later. How far from the base of the tree does it land? How high is the tree? How fast was the banana moving vertically as it hit the ground?
4. A diver running 2.1 m/s dives out horizontally from the edge of a vertical cliff and 3.5 seconds later reaches the water below. How high was the cliff?
5. A ball thrown horizontally at 29 m/s from the roof of a building lands 42 meters from the base of the building. How high is the building?
6. A soccer ball is thrown horizontally from the roof of a building 43 meters tall and lands 38m from the base. What was the ball's initial speed?
7. A projectile is launched horizontally with a speed of 63 m/s. If the projectile is launched 1.8 meters above the floor, how long does it take the projectile to hit the floor?
8. A bullet is fired horizontally at a speed of 200 m/s toward a target 125 meters away. How far below does it strike the intended target? How long does it take to reach that point?
