The Super Sled travels with an initial kinetic energy of 3369 J horizontally and to the right along a frictionless flat surface, initially at a height of zero (initial gravitational potential energy = 0). The driver briefly engages the rocket over a distance (Ax) of 2.000 m, pushing the sled with a force of 400.0 N over that distance. The rocket is then turned off. The sled then goes up an inclined surface with a rough surface. The coefficient of kinetic friction on the incline is uk. At the top of the incline, the sled reaches a height h = 1.500 m above the ground where the surface becomes flat and frictionless again. The sled (including the rocket and driver) has a total mass of 87.00 kg. (Notes: assume that g = 9.810 m/s² , and that the mass of fuel used by the rocket is negligible. Do not use scientific notation).

A student skates up a ramp that makes an angle 30° with the horizontal.

Consider the system shown below (Figure 1). The rope and pulley have negligible mass, and the pulley is frictionless. Initially the 6.00 kgkg block is moving downward and the 8.00 kgkg block is moving to the right, both with a speed of 0.600 m/sm/s. The blocks come to rest after moving 3.50 mm. Use the work-energy theorem to calculate the coefficient of kinetic friction between the 8.00 kgkg block and the tabletop.
