A chair of weight 75.0 N lies atop a horizontal floor; the floor is not frictionless. You push on the chair with a force of F = 38.0 NN directed at an angle of 34.0 DEGREES below the horizontal and the chair slides along the floor. Using Newton's laws, calculate nnn, the magnitude of the normal force that the floor exerts on the chair.
A 2.60 kg block is initially at rest on a horizontal surface. A horizontal force F of magnitude 7.29 N and a vertical force P are then applied to the block (see the figure). The coefficients of friction for the block and surface are us = 0.4 and Pk = 0.25. Determine the magnitude of the frictional force acting on the block if the magnitude of P is (a)6.00 N and (b)8.00 N. (The upward pull is insufficient to move the block vertically.)

A man wants to move a heavy wooden crate (82 kg) across a wooden floor. However, since he is taller than the crate, he must pull it using a rope that makes an angle of 42 degrees with the horizontal. He exerts a force of 312 N as he pulls. What is the Normal Force exerted by the floor on the crate? What is the size of the Friction Force felt by the crate, if the crate moves at a constant speed in a straight line? Imagine that instead the floor is more slick, so that the crate feels a friction force half of what you calculated above. What is the crate’s acceleration?
Two workers are sliding 390 kg crate across the floor. One worker pushes forward on the crate with a force of 450 NN while the other pulls in the same direction with a force of 290 NN using a rope connected to the crate. Both forces are horizontal, and the crate slides with a constant speed. What is the crate's coefficient of kinetic friction on the floor?
In the figure here, a box of Cheerios (mass mc = 1.70 kg) and a box of Wheaties (mass mw = 2.60 kg) are accelerated across a horizontal surface by a horizontal force applied to the Cheerios box.

An SUV containing 5 passengers has a mass of 3500 kg. It has a driving force of 2500 N directed west on a perfectly horizontal road. The surface of the road exerts a resistive force of 500 N due east. At the same time, a strong wind is blowing a force of 500 N due east in the opposite direction of the car's drive force. Does the car have any acceleration? If yes, then what is the magnitude and direction of the car's acceleration?
