A man exerts a horizontal force of 112 N on a refrigerator of mass 42.0 kg. If the refrigerator doesnt move, what is the minimum coefficient of static friction between the refrigerator and the floor? (See Section 4.6.)
A dockworker loading crates on a ship finds that a 20.0-kg crate, initially at rest on a horizontal surface, requires a 75.0-N horizontal force to set it in motion. However, after the crate is in motion, a horizontal force of 60.0 N is required to keep it moving with a constant speed. Find the coefficients of static and kinetic friction between crate and floor.
If a constant, nonzero force is applied to an object, what can you say about the velocity and acceleration of the object?

(a) Calculate its the magnitude of acceleration in a vertical takeoff from the Moon. (b) Could it lift off from Earth? If not, why not? If it could, calculate the magnitude of its acceleration.
Describe two examples in which the force of friction exerted on an object is in the direction of motion of the object.
On an airplanes takeoff, the combined action of the air around the engines and wings of an airplane exerts an 8 000-N force on the plane, directed upward at an angle of 65.0 above the horizontal. The plane rises with constant velocity in the vertical direction while continuing to accelerate in the horizontal direction. (a) What is the weight of the plane? (b) What is its horizontal acceleration?
The force on a baseball as with a bat can be more than 8,000 lb. No human can push on a bat with that much force. What is happening in this instance?
Shown below is a 10.0-kg block being pushed by a horizontal force of magnitude 200.0 N.The coefficient of kinetic friction between the two surfaces is 0.50. Find the acceleration of the block.
As a horse and wagon are accelerating From rest, the horse exerts a force of 400 N on the wagon (Figure 2.56), Illustrating Newton's third law, the wagon exerts an equal and opposite force of 400 N. Because the two forces are in opposite directions, why don't they cancel each other and produce zero acceleration (i.e., no motion)?
