A horizontal spring-mass system has low friction, spring stiffness 210 N/m, and mass 0.5 kg. The system is released with an initial compression of the spring of 12 cm and an initial speed of the mass of 3 m/s.

(a) What is the maximum stretch during the motion? m (b) What is the maximum speed during the motion? m/s (c) Now suppose that there is energy dissipation of 0.01 J per cycle of the spring-mass system. What is the average power input in watts required to maintain a steady oscillation? watt
