We know that Distance is given by second equation of motion ,

S = u t + \frac{1}{2} a t^{2}

Here

S = ? =

Distance

u = 0

= initial velocity

a = 3 m / s^{2}

= acceleratin

t = 8 s =

time

So, using the equation we get

S = u t + \frac{1}{2} a t^{2}

\Rightarrow S = 0 + \frac{1}{2} \times 3 \times 8^{2}

\Rightarrow S = 96 m
