$2\mathrm{.}1$ Car A accelerates uniformly from rest for $5$ weconst $C$ ar $B$ bepins to

from $5$ seconds after Car A begnen. The positiontume orach showing the

motion of Cars A and $B$ is given below $($not to scalle$)$

$2\mathrm{.}1\mathrm{.}1$ Define velocity.

$2\mathrm{.}1\mathrm{.}2$ Calculate the magnitude of the acceleration of CarA in the first

$5$ seconds.

$2\mathrm{.}1\mathrm{.}3$ Compare the positions of the cars at $5$ seconds.

$2\mathrm{.}1\mathrm{.}4$ Calculate the speed that Car A reaches after $5$ seconds.
