A 7.3 kg crate is moved rightward across a horizontal surface by a horizontal force such that it has constant velocity. If the coefficient of the kinetic friction is 0.58, calculate the magnitude of the kinetic friction force.

A 250-N force is directed horizontally as shown to push a 29-kg bunny up an inclined plane at a constant speed. Determine the magnitude of the normal force, FN, and the coefficient of kinetic friction, µk. The angle of incline is 27 degrees.

A 6.00 kg box is pulled horizontally with a 40.0 N force that makes an angle of 50.0° with the horizontal. The coefficient of kinetic friction between the surface and the box is 0.230. Calculate the magnitude of the normal force and the acceleration of the box.

You are driving a car at a constant speed of 14.0 m/s along a straight level road. As you approach anintersection, the stoplight turns red and you slam on breaks and the wheels lock and you skid to a stop in25.0 m. What is the coefficient of kinetic friction between your tires and the road?

A child has mass 6.0 kg and slides down a 35° incline with constant speed under the action of a 34-N force acting up and parallel to the incline. What is the coefficient of kinetic friction between the child and the surface of the incline?

A person slides a bottle with mass 0.20 kg along a level table.  It leaves his hand at 2.8 m/s and comes to a halt after going 1.0 m.  Find the coefficient of kinetic friction between the bottle and the table.

A snowboarder and his board with a combined mass of 50.0 kg moving at 9.50 m/s are about to go up an incline of angle 34.9 degrees, but due to friction only make it up a vertical height of 2.00 m. What was the coefficient of friction?

must be used? Ans: 39 N Question 12. A skier is pulled up a slope at a constant velocity by a tow bar. The slope is inclined at 24.2° with respect to the horizontal. The force applied to the skier by the tow bar is parallel to the slope. The skier's mass is 56.7 kg, and the coefficient of kinetic friction between the skis and the snow is 0.140. Find the magnitude of the force that the tow bar exerts on the skier. Ans: 299 N What is the

An object moves with an initial speed of 5.01 m/s. It then enters a region with friction causing the object to come to rest after moving 2.56 m. What is the coefficient of friction?

A box of mass mb is being blown by a strong steady wind across the level surface of a picnic table. The wind exerts a constant horizontal force of magnitude Fwb. As the block slides it accelerates with a magnitude ab. Assuming that kinetic friction is acting, develop an expression for the coefficient of kinetic friction µk between the box and table. Your final answer should be in terms of mb, Fwb, ab and g.
