A 0.4 kg mass connected to a low mass horizonal spring of stiffness 200 N/m slides on a very low friction surface. You observe the system at a moment when the spring is compressed 10 cm and the speed of the mass is 3 m/s. What will the kinetic energy of the mass be when the spring is stretched 5 cm?
