A car starts from rest to cover a distance $s$ . The coefficient of friction between the road and the tyres is $μ$ . The minimum time in which the car can cover the distance is proportional to:

Options:

Answer:

Solution:

Maximum acceleration is
$a = μg$
then
$s = \frac{1}{2} a t^{2}$
gives
$t = \frac{2 s}{μg} \propto \frac{1}{μ} .$
