Solution

The correct option is D $6 m$
We have, $s = u t + \frac{1}{2} a t^{2} = (2.5) (2) + \frac{1}{2} (0.50) (2)^{2}$
$s = 6 m$
Hence, distance travelled by the particle is $s = 6 m$

The correct option is D $6 m$
We have, $s = u t + \frac{1}{2} a t^{2} = (2.5) (2) + \frac{1}{2} (0.50) (2)^{2}$
$s = 6 m$
Hence, distance travelled by the particle is $s = 6 m$
