A cup of coffee has a mass of 0.377 kg. If you place this cup of coffee on a desk and let is sit there undisturbed, how much force is the desk exerting on it?

A 1400-kg car is brought from 25 m/s to 10 m/s over a time period of 5.0 seconds. Determine the force experienced by the car.

(a) When rebuilding her car's engine, a physics major must exert 440 N of force to insert a dry steel piston into a steel cylinder. What is the magnitude of the normal force in newtons between the piston and cylinder? (b) What is the magnitude of the force in newtons she would have to exert if the steel parts were oiled?

As shown above an adhesive has been applied to contacting faces of two blocks so that the blocks interact with an adhesive force that has a magnitude, Fadhesion. A tension, T, is exerted by a wire attached to the upper blocks causing the blocks to remain at rest. The two blocks have weights, Wbottom  and Wtop. Which of the following must be true?   Wtop=T Wbottom=Fadhesion T=Wtop−Fadhesion T=Wbottom+Wtop+Fadhesion

the total aerodynamic force F acting on the airplane has a magnitude of 6250 lb. Resolve this force into vertical and horizontal components

A physics student watches a 1 g object go from rest to 1 mm/s in 1 sec. What is the force that caused this motion?

The Johnsons just received a heavy package (perhaps a treadmill) in the mail that they ordered from a popular online shopping website. It's so heavy that they had to push it across their carpeted floor since it was too heavy to lift. The item weighs 92.3 kg and it's packaged in cardboard. The coefficient of friction between the cardboard and their carpet is 0.71. They're a team, and they all push the huge package across their living room at a constant speed. How much collective force do they have to use to push the package across the living room at a constant speed of 0.07m / s Use the approximation g = 10m / (s^ 2)

A stack of books of total mass 3.13kg is placed on a table as seen in A. It is then placed on a sturdy piece of wood inclined at an angle of 15 degrees (refer to B). What is the ratio of the normal force in A to the normal force in B?

Consider the 63.6-kg mountain climber in the Figure below. Assume the given angle of the rope from the rock wall is 33.5 degrees instead of 31 degrees; likewise assume the angle of the climbers legs from vertical is 11.4 degrees instead of 15 degrees. Find the force that the mountain climber must exert with her feet in pounds on the vertical rock face to remain stationary. Assume that the force is exerted parallel to her legs. Also, assume negligible force exerted by her arms. 31 15 Type your answer...

In England in the Middle Ages an extensive system of canals was used for transportation. Some of these canals crossed over canyons by flowing over bridges (viaducts). Suppose that a heavily loaded barge crossed over such a waterway bridge. A) The force on the barge would become less because some water would be squeezed off of the bridge. B) The force downward on the bridge would increase because of the added weight of the barge. C) The force on the bridge would not change when the barge passed over. D) The force on the bridge would become less because of the buoyancy effect of the water on the barge. E) Whether or not the force on the bridge would increase or decrease would depend on whether the water was flowing or stationary.
