The 14.2-in. spring is compressed to a 6.9-in. length, where it is released from rest and accelerates the sliding block A. The acceleration has an initial value of 250 ft/sec² and then decreases linearly with the x-movement of the block, reaching zero when the spring regains its original 14.2-in.length. Calculate the time t for the block to go (a) 3.65 in. and (b) 7.3 in.
