A 50kg wooden crate is being pushed up a ramp with a force of 100N (parallel to the ramp) and is initially moving up the ramp at 5.0m/s. The coefficient of kinetic friction is 0.3 and the ramp slopes up at an angle of 20deg from level ground. Will the crate speed up, slow down, or move at a steady pace? Be sure your wor is well supported

For each of the situations given, state whether frictional forcesdo positive, negative, or ze ro work on the italicized object.(a) A plate slides across a table and is brought to rest by friction. (b) A person pushes a chair at constant speed across a rough, horizontal surface. (c) A box is set down on a stationary conveyor belt. The conveyor belt is then turned on and the box begins to move, being carried along by the belt. (d) A personexerts a horizontal force on a banana at rest on a counter top.The banana remains at rest.

Suppose a box is pushed along an inclined plane of angle θ and then letgo. If it has an initial velocity of 10.0 m/s, how far will the box movealong the plane if the coefficient of kinetic friction is 0.200?

wo blocks are positioned on surfaces, each inclined at the same angle of 52.3 degrees with respect to the horizontal. The blocks are connected by a rope which rests on a frictionless pulley at the top of the inclines as shown, so the blocks can slide together. The mass of the black block is 3.16 kg, and the coefficient of kinetic friction for both blocks and inclines is 0.440. Assume static friction has been overcome and that everything can slide. What is must be the mass of the white block if both blocks are to slide to the LEFT at an acceleration of 1.5 m/s^2?     2.34 kg     1.66 kg     10.38 kg     5.97 kg
