If the same plot is of displacement (x) versus time (t), indicate whether the body is at rest or in motion and whether it has uniform velocity or variable velocity in the rigions OA, AB, BC and CD.Find the distance described in 8 s.What is the displacement of the body in 8 s ?

Answer

In OA velocity is constant in AB it is zero , in BC it is constant and -ve and in CD it is variable . Distance =9 m .Displacement = -3 m
