A car, start from rest, accelerates in straight line at a constant rate of $2.0 m/s^2$

How far will the car travel in 10 seconds

use

$d=vt+\dfrac{1}{2}at^2\quad v=0\quad a=2\,m/s^2\quad t=10$

then

$$d=(0)(10\, s)

+\dfrac{1}{\cancel{2}}\left(\dfrac{\cancel{2}m}{\cancel{s^2}}\right)(10^2\cancel{s^2})

=100\, m$$

ok I know this relatively easy but it still new to me so hopefully ok
