A 118kg boxsits on a flat surface where it has a static friction coefficient ofμs= 0.524and a kinetic friction coefficient ofμk= 0.318.What is the minimum horizontal force that a worker must apply in order to get the boxtobegin moving

A 4.0kg object is moving across a friction-free surface with a constant velocity of 2ms–1. How much the horizontal forces is needed to maintain this state of motion?

You are helping a friend move. Consider two boxes which have masses in factors ofm; one of mass 6m and the other of mass 7m. The coefficient of static friction betweenthe two boxes is very large. The coefficient of static friction between the boxes and thefloor is 0.7 and the coefficient of kinetic friction is 0.1. You place the large box on top ofthe small box and slide them down a 1m high ramp out of the truck. The ramp isfrictionless because it is covered with wheels. The box slides down this ramp smoothlyonto the horizontal grass with coefficient of kinetic friction is 0.142857142857143. Howfar (in meters) will the boxes slide before they stop?

A block of mass m = 14kg rests on an inclined plane with a coefficient of static friction of mu_{s} = 0.11 between the block and the plane. The inclined plane is L = 6.8m long and it has a height of h = 3.95 m at its tallest point a. What angle in degrees does the plans make with respect to the horizontal B.what is the magnitude of the normal force, Fn in newtons that acts on the block C. What component of the force of gravity along with the plan fgx in newton? Will the block slide?

A 756 N person travels in his vehicle through a deep circular-shaped dip in the road. When the vehicle passes through the lowest point of the 50.0 m dip, the seat exerts an 1110 N force on the person. Determine the speed of the vehicle at this point.

Question 8. A 5.41-kg box is sliding across the horizontal floor of an elevator. The coefficient of kinetic friction between the box and the floor is 0.369. Determine the kinetic frictional force that acts on the box when the elevator is (a) stationary, (b) accelerating upward with an acceleration whose magnitude is 2.64 m/s², and (c) accelerating downward with an acceleration whose magnitude is 2.64 m/s².Ans: 19.56 N; 24.83 N; 14.29 N

A 10.1 kg box is released on a 49.9° incline and accelerates down the incline at 0.07 m/s². What is the coefficient of kinetic friction between the two surfaces?

A 74507450‑kg car is travelling at 28.728.7 m/s when the driver decides to exit the freeway by going up a ramp. After coasting 404404 m along the exit ramp, the car's speed is 13.513.5 m/s, and it is ℎ=10.7h=10.7 m above the freeway. What is the magnitude of the average drag force ?dragFdrag exerted on the car?

At Ted's request, Bill pushes the pizza box across the granite countertop towards Ted. When the box leaves Bill's hand it is sliding at 2.60 m/s. The box comes to rest over a distance of 110 cm. What is the coefficient of kinetic friction, uk, between the pizza box and the countertop? (Ignore air drag.)
