Not enough information. Most important would be the coefficient of friction between the tires and the roadway.

Otherwise you'd need starting and ending energies. Without entry speed, you don't have starting energy. Without information on how much work is done during the deformation, you don't have ending energy.

Are the skid marks from the truck or the car? Assuming the truck:

W = F(f) * d

W = F(N) *mu * d

W = g*2700kg * mu * d

W = (9.81m/s^2)(2700kg) mu * 22m

W = 583000J * mu

One site, http://www.engineeringtoolbox.com/friction-coeffic... suggests that dry tires have a coefficient of friction near 1. If so:

W = 5.83x10^5J

i am not quite sure but i feel skid marks of 22 m has no role work done is given by f.ds .the force is 6900n and 0.6m of movement as when car and truck moved together after docking...

work done= 2900*0.6 j=1740 J
