A car accelerates from rest uniformly and attains a maximum velocity of 2 ms–1 in 5 seconds. In next 10 seconds it slows down uniformly and comes to rest at the end of 10th second. Draw a velocity-time graph for the motion. Calculate from the graph (i) acceleration, (ii) retardation, and (iii) distance travelled.

Answer:
Initially the car moves under acceleration for 5 sec. So, the velocity-time graph has a slope in first 5 sec and then it moves at a constant speed. So, the curve will be a straight line parallel to time axis where the value of speed does not change.
