What is the coefficient of static friction

Reference no: EM13536838

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
