A formula used to determine the velocity v in feet per second of an object neglecting air resistance after it has fallen a certain height is v=√2gh, where g is the acceleration due to the gravity and h is the height the object has fallen. If the acceleration g is due to gravity on earth is approximately 32 feet per second, find the velocity of a bowling ball after it has fallen 80 feet..

Solution:

                  v = √(2*32*60) = 61.9677 ft/sec
