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

The graph given alongside shows the positions of a body at different times. Calculate the speed of the body as it moves from :

(a) A to B,

(b) B to C, and

(i) 0 t o 5 s

(i i) 5 s t o 7 s

(i i i) 7 s t o 9 s

Time (s)	0	1	2	3	4	5	6	7
Displacement (m)	2	6	12	12	12	18	22	24

t = 1 s, 2 s

3 s

The figure shows the displacement-time graph of a body moving in a straight line. Which of the following shows the corresponding velocity-time graph?
