Graphical representation-Motion in 1 d

Question

Figure shows the graph of the x-coordinate of a particle going along the x-axis as function of time.
The speed of particle at t = 12.5 s (in ms^-1) is ………..

Moderate

Solution

At B, velocity is 2 ms^-1
$slope of AB = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} = \frac{0 - 8}{16 - 12} = - 2 m / s$
As speed is always positive.
So, speed of particle at t = 12.5 s is 2 ms^-1
