An 8-kg sled is initially at rest on a horizontal road. The coefficient of kinetic friction between the sled and the road is 0.4. The sled is pulled a distance of 3 m by a force of 40 N applied to the sled at an angle of 30° to the horizontal.

(a) Find the work done by the applied force.

(b) Find the energy dissipated by friction.

(d) Find the speed of the sled after it has traveled 3 m.
