Using the first definition of coefficient of elasticity given in the lab (based on velocity), if a ball strikes a surface with a speed of 10 m/s and rebounds just after the collsion with a speed of 3 m/s, what is the coefficient of elasticity

e = 0.3

Explanation:

Given:

- The strike speed vi = 10 m/s

- The rebound speed vf = 3 m/s

- The coefficient of elasticity = e

Find:

what is the coefficient of elasticity

Solution:

- The coefficient of elasticity e is given as a ratio of after and before impact speeds.

                                      e = v_f / v_i

- The coefficient of elasticity for the given cas is as follows:

                                      e = 3 / 10

                                     e = 0.3

- The after impact speed is 3 tenth of the strike speed
