A mass-spring system oscillates such that the mass moves on a rough surface having coefficient of friction μ. It is compressed by a distance a from its normal length and, on being released, it moves to a distance b from its equilibrium position. The decrease in amplitude for one half-cycle (–a to b) is:
- \(\frac{\mu m g}{k}\)
- \(\frac{2 \mu m g}{k}\)
- \(\frac{\mu g}{k}\)
- \(\frac{\boldsymbol{k}}{\mu m g}\)
Answer
(B) 2 m g k
