A point starts moving in a straight line with a certain acceleration. At a time t after beginning of motion the acceleration suddenly becomes retardation of the same value .The time in which the point returns to the intial point is

Dear Student,
=> a = acceleration
From the Newton’s First Law of equation,
V =u+at
V = -at
Then t = -v/a
here now a becomes retardation.
Cheers!!
