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 ?

1.	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 ?
Answer» Solution :A straight line INCLINED with the time-AXIS for uniformly ACCELERATED motion, parallel to the time- axis for UNIFORM motion.
