A 0.620-kg wood block is firmly attached to a very lighthorizontal spring (k = 180 N/m) as shown in Fig. 8-35.This block-spring system, when compressed 5.0 cm andreleased, stretches out 2.3 cm beyond the equilibrium positionbefore stopping and turning back. What is the coefficientof kinetic friction between the block and the table?
