Question
A car accelerates from rest at a constant rate 
for some time, after which it decelerates at a constant rate 
and comes to rest. If the total time elapsed is 
then the maximum velocity acquired by the car is
The correct answer is:
Let the car accelerate at rate 
for time 
then maximum velocity attained,
Now, the car decelerates at a rate 
for time 
and finally comes to rest. Then,
