Question

Initial velocity , u = 0 m/s

Final velocity , v = 144 Km/h

Convert Km/h into m/s by multiplying with ⁵/₁₈

$$\begin{lgathered}\to\ \rm v=144\times \dfrac{5}{18}\ m/s\\\\\to\ \rm v=8\times 5\ m/s\\\\\to\ \rm v=40\ m/s\end{lgathered}$$

Time , t = 5 min

Convert min into seconds

$$\begin{lgathered}\to\ \rm t=5\ min\\\\\to\ \rm t=5\times 60\ s\\\\\to\ \rm t=300\ s\end{lgathered}$$

Acceleration , a = ? m/s²

Displacement , s = ? m

Apply 1st equation of motion ,

$$\begin{lgathered}\to\ \rm v=u+at\\\\\to\ \rm 40=0+a(300)\\\\\to\ \rm 40=300a\\\\\to\ \rm 4=30a\\\\\to\ \rm a=\dfrac{2}{15}\ m/s^2\ \; \bigstar\\\\\rm \to\ a=0.134\ m/s^2\end{lgathered}$$

Apply 3rd equation of motion ,

$$\begin{lgathered}\to\ \rm v^2-u^2=2as\\\\\to\ \rm (40)^2-(0)^2=2\bigg(\dfrac{2}{15}\bigg)s\\\\\to\ \rm 1600=\dfrac{4s}{15}\\\\\to\ \rm 400=\dfrac{s}{15}\\\\\to\ \rm s=6000\ m\ \; \bigstar\end{lgathered}$$​
