1. The problem statement, all variables and given/known data A horizontal spring-mass system has low friction, spring stiffness 165 N/m, and mass 0.2 kg. The system is released with an initial compression of the spring of 7 cm and an initial speed of the mass of 3 m/s. (a) What is the maximum stretch during the motion? (b) What is the maximum speed during the motion? (c) Now suppose that there is energy dissipation of 0.02 J per cycle of the spring-mass system. What is the average power input in watts required to maintain a steady oscillation? 2. Relevant equations Ei = Ef + W .5KSf^2 = .5 KSi^2 + .5mv^2 3. The attempt at a solution (a) .5KSf^2 = .5*165*.07^2 + .5*.2*3^2 .5KSf^2 = 1.304 s = .13m (b) Kf+0 = answer from part a, step 2 (in this case 1.304 J) .5mv^2 = 1.304 v = 3.611 m/s (c) I was not sure what to do and have not attempted this part.
