6 points PSE6 7.P031. 4. My Notes A 38.0 kg box initially at rest is pushed 5.20 m along a rough, horizontal floor with a constant applied horizontal force of 135 N. If the coefficient of friction between box and floor is 0.300, find the following. (a) the work done by the applied force (b) the increase in internal energy in the box-floor system due to friction (c) the work done by the normal force J (d) the work done...
Starting from rest, a 3.2-kg box is pushed on a horizontal floor with a force of 482.6 N parallel to the floor. The coefficient of kinetic friction between the box and the floor is 0.5. What is the kinetic energy of the box after it has been pushed with the constant force of 5.8 meters?

3) A box of 25 kg is pushed horizontally, with a force of 200 N, up a 37degrees (with respect to the horizontal) frictionless incline. a) Find the Normal force What is the acceleration of the box? b) Now if friction is present. What value of the coefficient of kinetic friction is necessary such that the box is pushed with constant velocity.
In a garden nursery a large box of flower seeds (mass 18kg) is pushed 1.6m along a horizontal floor by a woman who is exerting a force of 1.5E2 N at 22o below the horizontal. The coefficient of kinetic friction between the box and the floor is 0.55. a) Use Newton's laws of motion to determine the magnitudes of the normal force and friction force on the box. b) use conservation of energy to determine the final speed of the...

A box with a mass of 10 kg is pushed with a constant force of 100 N a distance of 3.0 m up a ramp that makes an angle of 30 from the horizontal. The coefficient of kinetic friction between the box and the ramp is 0.35. a. Compute the work done by each of the four forces acting on the box. b. Assuming the box starts at rest, determine the speed of the box at it reaches a distance...
A) A massless rope is tied to a 1.82 kg box sitting on a rough, horizontal surface. The rope is pulled with constant force F acting upward at an angle 15.8o to the horizontal. The coefficient of kinetic friction between the box and the surface is 0.217, and the box slides at constant speed along the table for a distance of 84.4 m. Find the total work done by F, in J. B)Josh, mass 143 kg, is racing against his...
A 6.4 kg crate is pushed with a constant horizontal force of 22 N on a flat surface with kinetic friction coefficient µk = 0.25. If it starts from rest, what is its speed after 12 meters? (Use the work-energy theorem; remember that the formula uses the total net work of all forces present).
