(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A horizontal spring-mass system has low friction, spring stiffness 250 N/m, and mass 0.4 kg. The system is released with an initial compression of the spring of 13 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?

watt

3. The attempt at a solution

i was able to solve a and b right but having problems with c. Thanks for looking.
