An 9.0 kg sled is initially at rest on a horizontal road. Thecoefficient of kinetic friction between the sled and the road is0.40. The sled is pulled a distance of 3.0 m by a force of 42 Napplied to the sled at an angle of 30° to the horizontal.
(a) Find the work done by the applied force.
? J
(b) Find the energy dissipated by friction.
? J
(c) Find the change in the kinetic energy of the sled.
? J
(d) Find the speed of the sled after it has traveled 3 m.
? m/s
