a car accelerates from rest at a constant rate 'a' for some time. after which it decelerates at a constant rate'b' and comes to rest. if the total time elapsed is t second, evaluate
1) the maximum velocity reached and
2) the total distance travelled.

max velocity=at
distance= 1/2 at^2+at1/2 bt^2 
32 metre
