Solve the below problem:
Q: A 1.5-kg block A rests on a 1.5-kg block B and is attached to a spring of constant 180 N/m. The coefficients of friction between the two blocks are µs = 0.95 and µk = 0.90 and the coefficients of friction between block B and the horizontal surface are 0.15 µs = and 0.10. µk = Knowing that the blocks are released from rest when the spring is stretched 100 mm, determine
(a) The velocity of block A as it reaches the position in which the spring is unstretched,
(b) The maximum velocity of block A.
