Hi Tushar

Ans.  total time = 2t0

Apply v = u + at and find the velocity after time to(u = 0) and then after finding v , use this v to find the time t for the rest of the motion by jst changing the sign of acceleration and again apply v=u + at (final velocity = 0 ) .

add up the two times to get the total time.

dear hanuma, Action and reaction act on two different bodies. Hence movement of each body is due to either action or reaction.
