A horizontal spring with stiffness 10 N/m has a relaxed length of 7 m. A mass of 0.8 kg attached to the spring travels with a speed of 4 m/s to compress the spring 3 m. Create a spring, mass, wall, and the floor. 4 Animate the oscillation of the spring-mass system for 5 seconds by showing changes in velocity and position. Plot the changes in kinetic energy and potential energy of the spring vs. the time.
