Crates A and B of mass 50 kg and 75 kg, respectively, are released from rest. The linear elastic spring has stiffness k = 500 N/m. Neglect the mass of the pulleys and cables and neglect friction in the pulley bearings.

If μk = 0.25 and the spring is initially stretched 1 m, how far does A slide before the system momentarily comes to rest?
