A car accelerates from rest at constant ...

A car accelerates from rest at constant rate of `2ms^(-2)` for some time. Immediately after this, it retards at a constant rate of `4ms^(-2)` and comes to rest. The total time for which it remains in motion is 3 s. Taking the moment of start of motion as t = 0, answer the following questions.
What is the maximum speed attained by the car ?

Statement-1 is True, Statement-2 is True, Statement-2 is a correct explanation for Statement-1
