    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 n^(th) second (n = 1, 2, 3 …………) versus n. What do you expect this plot to be during accelerated motion : a straight line or a parabola ?

    Check the correctness of the formula S=ut+1/3at^(2) where S is the distance , u is velocity , a is acceleration and t is time .

    A particle is moving on a straight line so that its distance s from a fixed point at any time t is proportional to t^n . If v be the velocity and 'a' the acceleration at any time , then (nas)/(n-1) equals
