$\textit{\large{\underline{\underline{QUESTION:}}}}$

:-A car is moving along a road at 8m/s.It then speeds up to 20m/s in 4s. What is the car's acceleration?

$\textit{\large{\underline{\underline{SOLUTION:}}}}$

$\textbf{\underline{Given,,}}</p><p>$

$\textbf{Initial speed,u=8m/s}$

$\textbf{Final speed,v=20m/s}$

$\textbf{Time taken,t=4s}$

$\textbf{\underline{We know,,}}</p><p>$

$\mathbf{\boxed{\blue{a=\frac{v-u}{t}}}}$

$\mathbf{\implies{a=\frac{20-8}{4}}}$

$\mathbf{\implies{a=4 ms^{-2}}}$

$\textbf{\underline{Hence,, Acceleration,}}</p><p>$

$\mathfrak{\boxed{\pink{a=4 ms^{-2}}}}$
