Question

A body initially at rest picks up a velocity of 20 m/s in 4 seconds, if it then continues uniform velocity for 6 seconds. (a) Plot a V-T graph (b) Find the acceleration and total distance covered by the body.

Answer 1

Explanation:

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.
