1. A ball is dropped from rest on a cliff and hits the ground 5 seconds later. Its speed is -49 m/s and it has fallen 122.5 meters. 2. A ball is thrown vertically up from a window ledge 30 meters above the ground with an initial speed of 10 m/s. After 2 seconds its speed is -9.6 m/s and it has risen 0.4 meters above the ledge. 3. A stone is dropped from a building and hits the ground 5 seconds later. Using the equation d = 1/2at^2, the height of the building is calculated to be 122.5 meters.
