A block of mass 1kg is attached to one end of a spring of force constant k=20N/m. The other end of the spring is attached to a fixed rigid support. This spring block system is made to oscillate on a rough horizontal surface (mu = 0.04). The initial displacement of the block from the equilibrium position is a =30cm. How many times the block passes from the mean position before coming to rest ? (g=10m//s^(2))

1.	A block of mass 1kg is attached to one end of a spring of force constant k=20N/m. The other end of the spring is attached to a fixed rigid support. This spring block system is made to oscillate on a rough horizontal surface (mu = 0.04). The initial displacement of the block from the equilibrium position is a =30cm. How many times the block passes from the mean position before coming to rest ? (g=10m//s^(2))
