Identify all the forces acting on the object and draw a free-body diagram of the object. A box is being dragged across the floor at a constant speed by a rope pulling horizontally on it. Friction is not negligible.

When a parachute opens, the air exerts a large drag force on it. This upward force is initially greater than the weight of the sky diver and, thus, slows him down. Suppose the weight of the sky diver is 986 N and the drag force has a magnitude of 1049 N. The mass of the sky diver is 101 kg. Take upward to be the positive direction. What is his acceleration, including sign?

(Questions 16-18) A 25 kg box is at the bottom of a frictionless incline that is 7 m long as shown and makes an angle of 20 degrees with the horizontal. A person applies a constant horizontal (NOT parallel to the incline, but horizontal) force to the box, starting from rest. It reaches the top of the ramp in 13 seconds. 16. Draw a free-body diagram of this situation showing all forces on the box. 17. What was the magnitude of the box's acceleration during this process? 18. What was the magnitude of the force applied by the person?

In Example 5.7, we pushed on two blocks on a table. Suppose three blocks are in contact with one another on a frictionless, horizontal surface as shown in the figure below. A horizontal force F is applied to m₁. Take m₁ = 2.00 kg, m₂ = 3.00 kg, m3 = 5.10 kg, and F = 16.0 N. (a) Draw a separate free-body diagram for each block.

(e) You are working on a construction project. A coworker is nailing up plasterboard on one side of a light partition, and you are on the opposite side, providing "backing" by leaning against the wall with your back pushing on it. Every hammer blow makes your back sting. The supervisor helps you put a heavy…

When a parachute opens, the air exerts a large drag force on it. This upward force is initially greater than the weight of the sky diver and, thus, slows him down. Suppose the weight of the sky diver is 965 N and the drag force has a magnitude of 1016 N. The mass of the sky diver is 98.5 kg. Take upward to be the positive direction. What is his acceleration, including sign?

Two blocks with masses m1= 50 kg , m2= 100 kg are connected with a rope. Blocks are pulled with a 20.0 N force making a=30.0 degree angle withhorizontal on a frictionless surface. first question: Show all the forces on the two blocks by drawing a seperate diagram for each block. second question: apply the newton rules and find the tension (T=?) in the rope in between the two blocks.

When an airplane is in level flight, its weight is balanced by a vertical “lift,” which is a force exerted by the air. How large is the lift on an airplane in such flight if the mass of the airplane is 1.20 x 103 kg? Draw a free body diagram of the airplane.

Directions: Draw the free-body diagram of the following situations presented. Situation #1: A rightward force is applied to a crate to push it across the floor at a constant speed. Ignore air resistance. Situation #2: A physics book glides to the right across a smooth table at a constant speed. Ignore air resistance.
