A 1 kg block situated on a rough incline is connected to a spring of spring constant 100 Nm^(-1) as shown in Fig. 6.17. The block is released from rest with the spring in the unstreched position. The block moves 10 cm down the incline before coming to rest. Find the coefficient of friction between the block and the incline. Assume that the spring has a negligible mass and the pulley is frictionless.
