Consider a car initially at rest, starts to move along a straight road first with acceleration
, then with uniform velocity and finally, decelerating at
, before coming to a stop. Total time taken from start to end is
. If the average velocity during that time is
, the car moved with uniform velocity for a time of
Text Solution
Verified by ExpertsThe correct answer is:
A
Average velocity of car, 

Average velocity,
