• Initial velocity, u = 0 m/s
• Acceleration, a = 3.0 m/s
• Time, t = 8.0 m/s
• Distance, s = ?

Using second equation of motion -

$\begin{gathered}\begin{gathered}\begin{gathered}\mapsto \sf\boxed{\bold{\pink{s =\: ut + \dfrac{1}{2} at^2}}}\\\end{gathered}\end{gathered}\end{gathered}$

Substituting the values in second equation,

we get -

$s = 0 \times 8.0 + \frac{1}{2} \times 3 \times (8.0) {}^{2} \\ \\ s = 0 \times \frac{1}{2} \times 3 \times 64 \\ \\ s = 3 \times 32 \\ \\ s = 96m$
