A physics major is cooking breakfast when he notices that the frictional force between the steel spatula and the Oiled Steel frying pan is only 0.350 N. Knowing the coefficient of kinetic friction between the two materials (0.03), he quickly calculates the normal force. What is it? ________N

What is the magnitude of the normal force the object is receiving from the surface if the coefficient of friction between the object and the surface it is on is 0.26 and it experiences a force of friction of magnitude 59.5N? Fn = unit

Problem 1: While training on the planet Dagobah, Luke Skywalker is asked by Yoda to hold a block with a mass of 6.80kg against a vertical wall using only the Force. Luke applies the Force with a magnitude of 115.0N at an angle of 52.0° with respect to the horizontal. Luke discovers that if the Force increases any more, the block begins to slide up the wall. What is the coefficient of static friction between the block and the wall? Assume that gravity on Dagobah is the same as gravity on Earth.

Three cables are used to tie the balloon shown in Figure. Determine the magnitude of the vertical force (P) exerted by the balloon at A, knowing that the tension in cable AD is 1.099 N. y1 = 4.3 m y2 = 2.2 m x1 = 4.4 m x2 = 3.1 m z = 5.8 m

Consider an object at rest on a rough horizontal surface. Which of the following is necessarily correct if we use the model of friction described in the videos and book? The force of friction on the object is smaller than or equal to μg FN, where μs is the coefficient of static friction and FN is the normal force exerted on the object by the surface. The force of friction on the object is proportional to the normal force exerted by the surface on the object. The force of friction on any object opposes motion; since the object is at rest, the force of friction is zero. The force of friction on the object is proportional to the object's weight, i.e. Ff = p.mg, where μs is the coefficient of static friction, m is the mass of the object, and g is acceleration due to Earth's gravity.

A person is trying to judge whether a picture (mass = 1.47 kg) is properly positioned by temporarily pressing it against a wall. The pressing force is perpendicular to the wall. The coefficient of static friction between the picture and the wall is 0.750. What is the minimum amount of pressing force that must be used?

An object with a mass of m placed on an oblique surface at an angle. We applied a horizontal force f = mg on the particle as shown. Assume that the friction force between the object and the surface is so large that the object remains in place? Find the vertical force FN and the friction force ff ? In terms of the static friction coefficient, what is the range of the angle at which the object remains stagnant?
