Answer
(C) $1.05 \times 10^4 N$
Work Step by Step
We know that
$a=\frac{v^2-v_{\circ}^2}{2s}$
We plug in the known values to obtain:
$a=\frac{(0m/s)^2-(18m/s)^2}{2(1m)}$
$a=-162m/s$
Now $F=(65Kg)(-162m/s^2)$
$F=-1.05\times 10^4N$
Thus, the magnitude of force on the driver is $1.05\times 10^4N$ and hence the correct option is (C).
