Use your calculator to solve the problem.When a ball with coefficient of restitution e is dropped from a height h meters onto a large flat surface, the time t from the first impact until the ball stops bouncing is given by t = 
seconds. Find the time it takes a ball with coefficient of restitution 0.28 to stop bouncing if it is dropped from a height of 79.3 centimeters. (Round to the nearest tenth.)
A. 22.4 seconds
