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. |
