= -0.100 m), the
A child's pogo stick (figure below) stores energy in a spring (k = 1.75 × 10* N/m). At position
spring compression is a maximum and the child is momentarily at rest. At position ® (x = 0), the spring is relaxed and the
(x1
child is moving upward. At position ©, the child is again momentarily at rest at the top of the jump. Assume that the
combined mass of child and pogo stick is 24.0 kg.
(a) Calculate the total energy of the system if both potential energies are zero at x = 0.
