A how much work is required to move it at constant speed 2 meters along the floor against a frictional force of 150 n.
A 2 kg crate rests on the floor.
Answer 1 45 kj part b how much work is required to move it at constant speed 5 0 m vertically.
B how much work is required to lift it vertically at constant speed 2 meters against the force of gravity.
The crate is a uniform cube with sides 1 21 m in length.
A 900 n crate rests on the floor.
A see the free body diagram for the crate as it is being pulled.
Number units number units.
A 550 kg crate rests on the floor.
Here s how to crack it the normal force on the object balances its weight so f n mg 100 kg 10 m s 2 1 000 n therefore f static friction max f f static max µ s f n 0 4 1 000 n 400 n.
A 1400 n crate rests on the floor.
Since the person is not moving.
A 1300 n crate rests on the floor.
What is the minimum height where the force f can be applied so.
Determine the magnitude of the normal force that a the floor exerts on the crate and b the crate exerts on the person.
A uniform crate with a mass of 16 2 kg rests on a floor with a coefficient of static friction equal to 0 571.
Part a part completehow much work is required to move it at constant speed 5 0 m along the floor against a friction force of 290 n.
Determine the magnitude of the normal force that a the floor exerts on the crate and b the crate exerts on the person.
If a force of 250 n parallel to the floor is applied to the crate what s the magnitude of the force of static friction on the crate.
How much work is required to move it at a constant speed a 4 0 m along the floor against a friction force of 180 n and b 4 0 m vertically.
Note that the view is one looking down on the top of the crate.
Since the crate is not accelerating horizontally.
Express your answer to two significant figures and include the appropriate units.

A horizontal force of 50 0 n accelerates the crate at 1 00 m s2.
How much work is required to move it at constant speed a 4 0 m along the floor against a friction force of 230 n and b 4 0 m vertically.
A 33 7 kg crate rests on a horizontal floor and a 65 6 kg person is standing on the crate.
Two forces and are applied to the crate and it begins to move the coefficient of kinetic friction.
A 720 j b 3600 j.
A 37 0 kg crate rests on a level floor.
This is the maximum force that.
A 100 n force is applied to the side of a crate resting on a level floor.
