Question

An object is moving along a straight line with uniform acceleration. The following table gives the velocity of the object at various instants of time:

Time (in sec.):	$0$	$1$	$2$	$3$	$4$	$5$	$6$
Velocity (in m/s):	$2$	$4$	$6$	$8$	$10$	$12$	$14$

Plot the graph. From the graph,

Find the velocity of the object at the end of $2.5$ seconds.
Calculate the acceleration.
Calculate the distance covered in the last $4$ seconds.

Answer

$\text{a}=\frac{\text{v}-\text{u}}{\text{t}}$$\text{a}=\frac{4-2}{1}=2\text{m/s}^2$
Now for,
$\text{t}=2.5$
$\text{a}=\frac{\text{v}-\text{u}}{\text{t}}$
$2=\frac{\text{v}-2}{2.5}$
$5=\text{v}-2$
$\text{v}=7$
