A car going at a speed of \( 7 \mathrm{~ms}^{-1} \) can be stopped by applying brakes in a shortest distance of \( 10 \mathrm{~m} \). Show that the total frictional force opposing the motion, when brakes are applied, is \( 1 / 4 \) th of the weight of the car. \( \left(g=9.8 \mathrm{~ms}^{-2}\right) \)
