A 30-kg box, initially at rest, is pulled 10 meters along a warehouse floor, by a 200-N pulling force that makes an angle, =20°, with the horizontal, as shown in the diagram below. The coefficient of kinetic friction between the box and the floor is =0.6.
1.How much work is done a) by the pulling force and b) by the friction force?
2.What is the final kinetic energy of the box?
3.What is the final velocity of the box?
