A chair weighing 150 rests on a level floor that is not frictionless. A man pushes on the chair with a force = 43.0 that is directed at an angle of 34.0 with the horizontal. Assume that the chair is stationary but is on the verge of sliding.
Using Newton's laws, calculate , the magnitude of the normal force that the floor exerts on the chair.
What is the coefficient of static friction, , between the floor and the chair? Recall that the chair is on the verge of sliding.
