$\textsf{A car, starting from rest, accelerates in a straight line at a constant rate of $\displaystyle 2.0 \frac{m}{s^2}$}$$\textit{How far will the car travel in $10$ seconds}$\begin{align*}\displaystyle
\Delta t&=10\\
a&=2\\
d_i&=0\\
v_i&=0\\
d_f&= d_i + v_i\Delta t + \frac{1}{2} a \Delta t^2\\
&=0+0\cdot 10+\frac{1}{2} \cdot 2\cdot 10^2\\
&=\color{red}{100 \, m}
\end{align*}no answer given so hope this is ok
