Question

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

(c) C to D.

Answer 1

(a) We know,

Slop of the distance time graph gives speed

From A to B

$Slope=\frac{3}{3}=1$ cm/s

(b) From B to C position of the body is not changing hence its speed is zero.

(c) Slop of the distance time graph gives speed

$Slope=\frac{7-3}{8-6}=\frac{4}{2}=2$ cm/s
