If you pull horizontally on a crate with a force of 200 N, it slides across the floor in dynamic equilibrium. How much friction is acting on the crate?

A rope one meter long rests on a table where the coefficient of friction is 0.50. What maximum length of rope can hang over the side before the whole rope will slip off?

A car traveling at 60 km/h hits a bridge abutment. A passenger in the car moves forward a distance of 79 cm (with respect to the road) while being brought to rest by an inflated air bag. What magnitude of force (assumed constant) acts on the passenger's upper torso, which has a mass of 42 kg? Number Units

A truck with a mass of 750 kg is traveling along a wet road at 30.0 m/s  The driver slams on the brakes and skids to a stop.  If the coefficient of kinetic friction between the tires and the road is 0.50: what frictional force stops the truck? how far does it skid?

A horizontal force of 734 N is needed to overcome the force of static friction between a level floor and a 132 kg crate. What is the acceleration of the crate if the 734 N force is maintained after the crate begins to move and the coefficient of kinetic friction is 0.07?

F 0 EC FAC $ Ed and Al are pushing on a couch as shown in the picture and it doesn't slip. Ed is pushing with a force of 198.9 N at an angle of 0 = 54 degrees with respect to the vertical and Al is pushing with a force of 60.2 N at an angle of = 35.4 degrees with respect to the horizontal. If the couch has a mass of 83 kg and the coefficients of static and kinetic friction between the couch and the floor are μg = 0.53, and k = 0.39, what is the magnitude of the force of friction exerted by the floor on the couch?

Antman must supply a force of 8.25x10-3N to a small computer chip to lower it at a constant velocity over a distance of 11.5cm down a slope into a waiting circuit board. If the computer chip has a mass of 5.50g and the slope makes an angle of 23.0° with respect to the horizontal. What is the coefficient of kinetic friction between the computer chip and the slope?

A rope exerts a force of 50 N on a box to keep it stationary. If the box is on a plane inclined 25° from the horizontal and the coefficient of static friction is 0.29, calculate the normal force exerted on the box.

A 26.8 kg box sits on a ramp at an angle of 13° above the horizontal. If the coefficient of static friction between the box on the ramp is 0.215, what minimum applied force is required to keep the box at rest?

A block of mass 1.45 kg is resting on a board with friction.The board is inclined until the mass just starts to slide.  If the angle of the incline when the mass just barely begins to slide is 17.5 degrees,what is the coefficient of static friction between the block and the board?
