An object is thrown vertically upward with a speed of 20 metres per second
from the edge of a cliff which is 80 metres high. The object just misses the
edge of thecliff on the way down and falls to the bottom of the cliff. Calculate

(b) the velocity of the object at the moment it just reaches the bottom
of the cliff.
