  • Q:

    A spring with a 1kg mass attached to it oscillates with an amplitude of 15 cm. The frictionless surface on which it oscillates is replaced with a surface with a μk of 0.25. If the spring oscillates through 20 periods before coming to a halt, what was the original energy of the system? Assume each of the 20 periods covers the same distance.
