Question

The following displacement - time graph shows the posiitions of a body at different times. Calculate the velocity of the body as it moves from
(i) A - B
(ii) B - C
(iii) C - D

Open in App

Solution

(1) A-B
Velocity is Displacement/time interval= $(3 - 0) / (5 - 2) = 1 m / s$
(2) B-C
Displacement is zero because at B and at C the value of displacement is 3 so no change in displacement so no velocity so velocity is zero.
(3) C-D

Velocity= $(0 - 3) / (10 - 7) = - 1 m / s$
