Chapter 5, Problem 64P

-m rope is tied to a tree; the other end is tied to a car stuck in the mud. The motorist pulls sideways on the midpoint of the rope, displacing it a distance of 2 m. If he exerts a force of 80 N under these conditions, determine the force exerted on the car.

Isaac pulls a 50 kg box containing the toy car as a gift of his father on his 10th birthday across a level floor with a force of 200 N. If the force acts at an angle of 30° up from the horizontal, and the coefficient of kinetic friction is 0.30, determine: the normal force exerted on the box by the floor; the frictional force exerted on the crate by the floor; the acceleration of the box.
If you press an apple crate against a wall so hard that the crate cannot slide down thewall, what is the direction of (a) the static frictional force fs on the crate from the wall and (b)the normal force FN on the crate from the wall? If you increase your push, what happens to (c)fs, (d) FN, and (e) fs,max?
Current Attempt in Progress In the figure, a crate of mass m = 88 kg is pushed at a constant speed up a frictionless ramp (0 = 31°) by a horizontal force F. The positive direction of an x axis is up the ramp, and the positive direction of a y axis is perpendicular to the ramp. (a) What is the magnitude of F? (b) What is the magnitude of the normal force on the crate? (a) Number i (b) Number i Units Units e 2012
