A 10 kg crate is pulled along a warchouse floor across a distance of 35 m by a horizontal rope. The force of the rope is 22.0 N; the block starts from rest. At the end of the 35 m, the final velocity of the block is 1.8 m/s. What is the coefficient of kinetic friction? (15 pts)
An object with a mass of 60.0 kg is pulled up an inclined surface by an attached rope, which is driven by a motor. The object moves a distance of 40.0 m along the surface at a constant speed of 3.5 m/s. The surface is inclined at an angle of 30.0° with the horizontal. Assume friction is negligible. (a) How much work (in kJ) is required to pull the object up the incline? kJ (b) What power (expressed in hp)...
A block of mass M is pulled over a rough horizontal surface. The block has a coefficient of kinetic friction with the surface of . The block is subject to the normal force, the friction force, the force of gravity, and a force from a rope of magnitude T which pulls up and to the right at an angle of 0 with the horizontal. The box was initially travelling to the right at speed v = 2.7 m. If M...
