Aperson pushes on a 57-kg refrigerator with a horizontal force of 267 n; the - sign indicates that the force points in the +x direction. the coefficient of static friction is 0.65. (a) if the refrigerator does not move, what are the magnitude and direction of the static frictional force that the floor exerts on the refrigerator? (b) what is the magnitude of the largest pushing force that can be applied to the refrigerator before it just begins to move?

To practice problem-solving strategy 10.1 for energy conservation problems. a sled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slides a distance d1 down the slope and then covers the distance d2 along the horizontal terrain before stopping. find the coefficient of kinetic friction μk between the sled and the ground, assuming that it is constant throughout the trip.
