A chair of mass 11.5 kg is sitting on the horizontal floor; the floor is not frictionless. You push on the chair with a force F = 35.0 Nthat is directed at an angle of 39.0 ∘ below the horizontal and the chair slides along the floor. Use Newton's laws to calculate the normal force that the floor exerts on the chair.

A uniform ladder stands on a rough floor and rests against a frictionless wall as shown in the figure. Since the floor is rough, it exerts both a normal force n, and a frictional force r, on the ladder. However, since the wall is frictionless, it exerts only a normal force N, on the ladder. The ladder has a length of L = 4.3 m, a weight of w. = 67.5 N, and rests against the wall a distance d...
