Answer 1

Explanation:

a) AB has acceleration achieve velocity Vo in t second, BC has uniform speed for t sec (duration of time 2t-t)

B) in BC section has zero acceleration because there is no change in velocity

C) use v=u+at In this condition v= 0; u=Vo; a=?, T=t

So, a = -Vo/t

D ) first calculate the distance travel at AB, afterwards Bc, and CD
