Free response 14. In a spring-mass system, a mass of 0.5 kg is pulled to 0.04 m to the right and released. The mass is now oscillating in SHM. The spring constant, k of the spring is 200 N/m. a) Find maximum velocity and maximum acceleration of mass. b) What are the velocity and the acceleration of mass when it is +0.03 m from equilibrium position and moving towards left (mass is right side of equilibrium position)? c) Calculate potential energy of spring and kinetic energy of mass for the situation in part (b). 16
