A child's pogo stick (figure below) stores energy in a spring (k = 1.60 x 10N/m). At position *, - -0.100 m), the spring compression is a maximum and the child is momentarily at rest. At position ® x = 0), the spring is relaxed and the 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 16.0 kg. (a) Calculate the total energy of the system if both potential energies are zero at x = 0. 64.32 (b) Determine 2 0.41 m (c) Calculate the speed of the child at x = 0. X Your response differs from the correct answer by more than 10% Double check your calculations. m/s (d) Determine the value of x for which the kinetic energy of the system is a maximum mm -9.8 (e) Obtain the child's maximum upward speed, 2.87 m/s
