A 100 N force, directed at an angle u above a horizontal floor, is applied to a 25.0 kg chair sitting on the floor. If u =0, what are (a) the horizontal component Fh of the applied force and (b) the magnitude FN of the normal force of the floor on the chair? If u =30.0, what are (c) Fh and (d) FN? If u =60.0, what are (e) Fh and (f) FN? Now assume that the coefficient of static friction between chair and floor is 0.420. Does the chair slide or remain at rest if u is (g) 0, (h) 30.0, and (i) 60.0?

Newton's Second Law

Newton’s laws of motion describe the relationship between the motion of an object and forces acting on it. Newton’s law of motion has two types as follows:
