The police estimate that for good road conditions the frictional force, F , on a skidding vehicle of mass, m, is given by F = 0.8mg . A car of mass 450 kg skids to a halt narrowly missing a child. The police measure the skid marks and find they are 12.0 m long. Calculate the deceleration of the car when it was skidding to a halt.
