The 12.2-in. spring is compressed to a 7.9-in. length, where it is released from rest and accelerates the sliding block A. The acceleration has an initial value of 170 ft/sec² and then decreases linearly with the x-movement of the block, reaching zero when the spring regains its original 12.2-in. length.
