Which of the following can we say about the friction component of the force the bottom box exerts on the top box? The friction component of the force the bottom box exerts on the top box has a magnitude between 10N and 20 N. There is no friction between the boxes because the top box is at rest with respect to the bottom box. The friction component of the force the bottom box exerts on the top box is exactly 20 N.

Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.

A stone has a mass of 8.79 g and is wedged into the tread of an automobile tire, as the drawing shows. The coefficient of static friction between the stone and each side of the tread channel is 0.818. When the tire surface is rotating at 10.9m/s, the stone flies out the tread. The magnitude FN of the normal force that each side of the tread channel exerts on the stone is 2.46 N. Assume that only static friction supplies the centripetal force, and determines the radius r of the tire (in terms of m)

An accident victim with a broken leg is being placed in traction. The patient wears a special boot with a pulley attached to the sole. The foot and boot together have a mass of 4.0 kgkg, and the doctor has decided to hang a m� = 6.6 kgkg mass from the rope. The boot is held suspended by the ropes and does not touch the bed. (Figure 1) Determine the amount of tension in the rope by using Newton’s laws to analyze the hanging mass. Assume that ϕ� = 11 ∘∘ .Hint: If the pulleys are frictionless, which we will assume, the tension in the rope is constant from one end to the other. The net traction force needs to pull straight out on the leg. What is the proper angle θ� for the upper rope? What is the net traction force pulling on the leg?
