A car of mass m travelling with a velocity v comes to rest over a distance d in time t. The constant frictional force acting on the car while it is braking is found using:

Newton's Second Law: F=maa=v-u/tUsing SUVAT equations: v 2 = u 2 +2asv (final velocity)=0 u(inital velocity)= v s=d Rearranging gives: -v 2 =2ad a=-v 2 /2d Therefore F= -mv 2 /2dNegative sign suggests the ca...
