A l0 kg. child bounces on an elastic band with an amplitude of 20 centimeters. The band has a force constant of 500 N/m. (aXl0) What is the period of oscillation? What is the frequency? (bX5) Find the maximum speed of the child. (cXl0) Suppose the initial amplitude is 20 centimeters. Each time the child's feet touch the ground, she pushes and increases her mechanical energy by 0.100 Joules. How much does her amplitude increase after 20 bounces?
