The 14.6-in. spring is compressed to a 7.4-in. length, where it is released from rest and accelerates the sliding block A. The acceleration has an initial value of 350 ft/sec² and then decreases linearly with the x-movement of the block, reaching zero when the spring regains its original 14.6-in. length. Calculate the time t for the block to go (a) 3.6 in. and (b) 7.2 in. 7.4" -14.6" wwwwwww Answers: To go 3.6 in., t= i To go 7.2 in., t= 0.065 sec ! sec
