What is the total force in pounds on the top surface of a box that has...
If a human body has a total surface area of 1.8 m', what is the total force on the body due to the atmosphere at sea level (1.01 x 10 Pa)?
An ordinary gasoline can measuring 30.0 cm by 25.0 cm by 20.0 cm is evacuated with a vacuum pump.Assuming that virtually all of the air can be removed from inside the can, and that atmospheric pressure is 14.7 psi, what is the total force (in pounds) on the surface of the can?
A small box with a weight of 25.0 Nis placed on top of a larger box that has a weight of SSO N. The system of two boxes is at rest on a horizontal surface (the larger box is in contact with the surface). You apply an additional downward force of 26.0 N to the top of the small box by resting your hand on it. For this problem, use - 10 N/kg. (a) What is the magnitude of the...
An airtight box has a removable lid of area 1.43E-2 m2 and negligible weight. The box is taken up a mountain where the air pressure outside the box is 8.41E+4 Pa. The inside of the box is completely evacuated. What is the magnitude of the force required to pull the lid off the box
A woman exerts a horizontal force of 10 pounds on a box as she pushes it up a ramp that is 4 feet long and inclined at an angle of 30 degrees above the horizontal.Find the work done on the box.
Question 1 (identifying forces) Box A is placed on a level surface. Box B is placed on top of box A a. Draw a free-body diagram for box B. Scale the length of the force vectors correctly. b. Draw a free-body diagram for box A. Scale the length of the force vectors correctly

A8 kg box is being pulled across a horizontal surface. The pulling force has a magnitude of 55 N and acts at an angle of 30° above the horizontal. The coefficient of kinetic friction between the surface and box is 0.2. What is the normal force acting on the box?
A box contains machinery that can rotate. The total mass of the box plus the machinery is m= 8 kg. A string wound around the machinery comes out through a small hole in the top of the box. Initially the box sits on the ground, and the machinery inside is not rotating (left side of the figure below). Then you pull upward on the string with a force of constant magnitude F= 133 N. At an instant when you have...
