Answer»

According to the problem, A body starting with a velocity ‘V’ returns to its initial position after‘t’ second with the same SPEED, along the same line.


LET US consider that the acceleration of particle is x.

V= U=+ xt

-V= V+ xt

xt = -2v

Hence, a= -2V/x


The acceleration of a particle is -2*Velocity/ seconds.
