A bulldozer is pushing a car and a truck sideways. the coefficientof kinetic friction between the car's and the truck's tries and thepavement is 0.9. the car has a mass of 1.70 x 10^3 kg and the truckhas a mass of 4.2 x 10^3 kg. when the bulldozer is pushing the twovehicles at a constant speed.
a) what force is the car exerting on the truck?
b) what force is the bulldozer exerting on the car?
c) what force is the pavement exerting on the bull dozer?
