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 s 0 95 and k 0 90 and the coefficients of friction between block B and the horizontal surface are 0 15 s and 0 10 k 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 k ISO N m B

Question: 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

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.

k = ISO N/m B
