Question

A point mass starts moving in a straight line with constant acceleration “a”. Atalib
after the beginning of motion, the acceleration changes sign, without chang7
magnitude. Determine the time t, from the beginning of the motion in which the
mass returns to the initial position. ((2 + 12 ) t) (AS)​

Answer 1

Answer:

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.
