The displacement x of a particle in rectilinear motion at time t is represented as x^(2) = at^(2) +2bt+c , where a ,b, and c are constants. Show that the acceleration of this particle varies (1)/(x^(3)) .

The acceleration of a particle starting from rest moving in a straight line with uniform acceleration is 8m//sec^2 . The time taken by the particle to move the second metre is:

The velocity of a particle moving in a straight path is given by v=16t-4t^(2) where v and t measured in ft/s and second units respectively. If the initial displacement be 10 ft, find the displacement of the particle in t seconds.
