A55-kg box is being pushed a distance of 7.0 m across the floor by a force whose magnitude is 160 n. the force is parallel to the displacement of the box. the coefficient of kinetic friction is 0.25. determine the work done on the box by each of the four forces that act on the box. be sure to include the proper plus or minus sign for the work done by each force.

The drag force, fd, imposed by the surrounding air on a vehicle moving with velocity v is given by fd = cdaρv 2/2 where cd is a constant called the drag coefficient, a is the projected frontal area of the vehicle, and ρ is the air density. an automobile is moving at v = 80 kilometers per hour with cd = 0.28, a = 2.3 m2, and ρ = 1.2 kg/m3.
