In the position shown, block A is moving to the left at a speed of 6 m/s, and the spring is not deformed. Determinate the stiffness of the k-spring, in N/m, which would cause the system to stop after A has shifted 0.8 m. The kinetic friction coefficient between block A and the horizontal surface is 0.25, and the weights of the pulleys are negligible. The mass of block A is 2.6 kg, and the mass of block B is 6.0 kg.
