... Example: A ball is projected vertically upwards with a speed of 49 m s-1 from the top of a cliff, which is 180 metres above the sea. As the ball comes down it just misses the cliff. In free fall the ball would have a terminal speed of 70 m s-1 , and the air resistance is proportional to the square o ...

For the purpose of determining the gravitational potential energy, let’s agree to select zero gravitational energy to be at the floor. Th ...
