Questions
A point mass starts moving in a straight line with constant acceleration. After time the acceleration changes its sign, remaining the same in magnitude. Determine the time from the beginning of motion in which the point mass returns to the initial position.
detailed solution
Correct option is B
If we start time calculations from point $P$ and apply the equation,s=ut+12at2 -12at02=+at0t+12(-a)t2 Solving we get, t=(2+1)t0 =2.414t0 Total time, T=t+t0 =(3.414)t0Talk to our academic expert!
