1. The response of a mass oscillating on a surface is measured. The initial position is measured to be 30 from its zero rest position, and the final position is measured to be 3.5 mm from its zero rest posi after four cycles of oscillation in 1s. Determine the coefficient of friction. Ans: p= 0.11 2. A 2 kg mass connected to a spring of stiffness 103 Nm-1 has a dry sliding friction force (Fc) of 3 N. the mass oscillates, its amplitude decreases 0.2 m. How long does this take? Ans: t = 4.78 s
