A car accelerates from rest at a constant rate A for some time after which it retards at a constant rate B to come to rest. If the time elapsed is T second,calculate the maximum velocity reached?(please try solving this problem by plotting velocity time graph and if you can then please explain how to do it)

Vmax = Vo + at.
Vmax = 0 + AT = AT.
