A three wheeler starts from rest, accelerates uniformly with 1 ms-2 on a straight road for 10 s and then moves with uniform velocity. Plot the distance covered by the vehicle during the nth second (n = 1, 2, 3, ...) versus n. What do you expect this plot to be during accelerated motion : a straight line or a parabola ?

Explanation

A straight line inclined with the time-axis for uniformly accelerated motion, parallel to the time- axis for uniform motion.
