Question

A car of mass 1200 kg is moving on the road at the speed of 60 km/h. If the coefficient of friction is 38 and the normal force is 50 N, the frictional force acting on the car is given by ______ .

Answer 1

Given,

$m=1200kg$

$v=60km/h$

$\mu =38$

$N=50N$ normal force.

The frictional force, $f_{\mu }=\mu mg$

$f_r=38\times 1200\times 9.8$

$f_r=4.46kN$
