A 6.0 kg sled is initially at rest on horizontal road. The coefficient of kinetic friction between the sled and the road is 0.40. The sled is pulled a distance of 3.0 m by a force of 37 N applied to the sled atan angle of 30° to the horizontal.
1. Find the work done by the applied force.
2. Find the energy dissipated by friction.
3. Find the change in the kinetic energy of the sled.
4. Find the speed of the sled after it has travelled 3 m.
In many locations, such as Lake Washington in Seattle, floating bridges are preferable to conventional bridges. Such a bridge can be constructed out of concrete pontoons, which are essentially concrete boxes filled with air, Styrofoam, or another ..
