A point mass starts moving in a straight line with a constant acceleration a. At a time `t_(1)` a fter the beginning of motion, the acceleration changes sign, remaining the same in magnitude. Determine the time t from the beginning of motion in which the point mass returns to the initial position.

A point mass starts moving in a straight line with constant acceleration "a". At a time t after the beginning of motion, the acceleration changes sign, without change in magnitude. Determine the time t_(0) from the beginning of the motion in which the point mass returns to the initial position. ((2+sqrt2)t)
