A constant pushing force P = 200 N is applied to a 20.0-kg box (see figure below). The box is sliding on a rough horizontal surface with a coefficient of friction of pk = 0.10. The box starts with an initial velocity to the right of vo= 2.00 m/s, and the force pushes the box a distance of 8.00 m. A. Calculate the net Work done on the box over this distance. B. Calculate the final speed of the box. (If you didn't solve part A, assume the net work is 1000 J) P 30° 20 kg |< -8.0 m-
