Question: Problem 4. (Oscillating mass on a spring B) A 4.0 kg mass at the end of a spring oscillates with an amplitude of 0.40

Problem 4. (Oscillating mass on a spring B) A 4.0 kg mass at the end of a spring oscillates with an amplitude of 0.40 m. It takes 2.0 seconds to make one complete oscillation. You can assume that at time t = 0 s the spring is maximally stretched. A. What is the spring constant of this spring? Express in N/m. 4 kg B. At what time does it pass the equilibrium position for the first time? Express your answer in seconds. C. What is the position of the mass at time t = 0.25 s? Express your answer in m. D. What is the maximum potential energy in the spring mass system? Express your answer in J. E. What is the maximum kinetic energy of the mass? Express your answer in J. F. What is the total energy in the system? Express your answer in J.
