(2) A stack of two crates is being lifted upwards by two cables, as shown in the figure below. The tension in each cable is 2270 N. You may assume that the masses of the cables are negligible compared to the masses of the crates. Do not use Newton's 3rd Law; use only Newton's 2nd Law. (a) Using Newton's 2nd Law, calculate the force that the top crate exerts on the bottom crate and the force that the bottom crate exerts on the top crate. (answer: Fotom on-top = Fiop-on-bottom= 3062 N) (b) The maximum tension that each cable can handle without breaking is 3230 N. Calculate the maximum upward acceleration that the load can have without breaking the cables. (answer: 8.97 m/s²) 232 kg 112 kg

An elevator is supported by a cable and moving downward through the elevator shaft at a constant speed. How does the upward tension force compare to the downward force of gravity? O The upward tension force is stronger than the downward force of gravity. The downward force of gravity is stronger than the upward tension force. The tension force and the force of gravity are of equal strength.

True or false? If two external forces that are both equal in magnitude and opposite in direction act on the same object, the two forces can never be a Newton’s third-law pair. True or false? In considering forces in systems, their direction is not important.

At a construction site, a pallet of bricks is to be suspended by attaching a rope to it and connecting the other end to a couple of heavy crates on the roof of a building, as shown in (Figure 1). The rope pulls horizontally on the lower crate, and the coefficient of static friction between the lower crate and the roof is 0.509. What is the weight of the heaviest pallet of bricks that can be supported this way? (Hint: Start by drawing appropriate free-body diagrams.) (Express your answer in pounds.) What is the friction force on the upper crate under the conditions given in Part 1? (Express your answer in pounds.)

What is the magnitude of the static friction force required to keep a 2.00 kg block resting on an inclined plane at an angle 25 degrees? If the angle was increased, such that the incline plane was steeper, would the magnitude of the static friction force required to hold the block at rest increase, decrease, or stay the same?
Consider the following statement: “The normal force on an object is always equal to the weight of the object.”Select all the reasons that this statement is false . The normal force is not always parallel to the force of gravity The normal force is independent of the force of gravity The normal force is only equal to the weight of the object when sitting on a horizontal surface and there are no other forces in the y-direction except gravity The normal force causes an acceleration and therefore does not interact with gravity
If the coefficient of friction between a 40.0 kg crate and the floor is 0.680, (a) what horizontal force must a worker exert to just start the motion of the crate? (b) If the worker maintains that force once the crater starts to move and the coefficient of kinetic friction between the surfaces is 0.500, what would happen to the crate?
