When moving a couch you exert a force of 400 N and push it 4 m. How much work have you done?

Work = Force x DistanceWork = 400 x 4
Work = 1600 Nm
Work = 1600 Joules
Work = 1600 J

What happens when you exert force on an abject and it exerts force on you?
According to Newtons 3rd law, "Every action has an equal and opposite reaction". if you exert force on an object, the object will exert an equal and opposite force on you. when the forces exerted by you and the object balance a state of equilibrium is attained. however if you exert a force greater than the weight of the body, the body begins to move and work is done.
In the force has a component in the opposite direction from the motion the work done is negative?
No the work done is still positive, the force exerted and the work done to exert that force is still the same. Its just that the other object is exerting more of a force on the object doing the work.
Is When a person swims through water no work is done true?
Work is sure done. For example, moving the arms to swim requires force - and the force is done over a distance.
What do you have to do to an object to make it start moving and what is this called in science?
To make an object start moving is called acceleration, and it is done by exerting force on that object.
On the pail when the person is holding the pail by the force F is moving forword how much work is done?
-no work is done because the force and displacement are making an angle of 90 so whrere angle is 90 no work is done

If you exert a force of 10 to lift a box of .9m how much work has been done?
The answer would depend on the units used for the force. Since these are not specified, it is not possible to answer the question.
When force is to the direction of motion no work is done?
No. Only if you are applying the same amount of force then there is no motion. If you are applying more force (the object is moving) then there is work being done.
How much is done if you exert a 25-N force to lift a ball 0.4 m in 2 s?
10 J (novanet)

How much work is done when a vertical force acts on a moving object horizontally?
It depends on the magnitude of the force and the mass of the object
How much work is done when vertical force acts on an object moving horizontally?
It depends on the magnitude of the force and the mass of the object
How much work is done when a vertical force acts on an object moving horizontally?
as work done is dot product of force and displacement so cos(90)=0;therfore work done is zero
