If a person tries to lift a heavy box for 5 seconds and can't make it budge the work done on the box is equal to the amount of energy the person uses?
true or false if a person tires to lift a heavy box for 5 seconds and can't make it budge,the work done on the box is equal to the amount of energy the person the person uses.
If you push on a box but the box moves backwards what kind of work is being done?
negative
A force of 20 N is required to lift a box the box is lifted from the floor to a shelf that is 2 m high the amount of work done is?
Work Done= Force applied x distance moved in direction of the force. so the work done should in this case be 40J
If you want to lift a 5-kg box to a height of 1 meters how much work must be done?
98 j
How much work is done if you lift a box weighing 100n on to a shelf that is 2 meters high?
Work = force x distance = 200 joules

How much work is done if you hold a 50lbs box for 5 hours?
No work is being done. Work is when an object moves in the same direction as the force applied to it.
How much work is being done if a 100 n box is lifted meters of the ground?
Work = force x displacementW = Fd W = 100N x 3m W = 300J 300 joules of work is done on the box.
How much work is being done if a 100 N box is lifted 3 meters of the ground?
Work = force x displacementW = Fd W = 100N x 3m W = 300J 300 joules of work is done on the box.
One situation in which no work is done to an object?
2 examples where no work is being done is:1) When an object is at rest, such as a ball on a flat plane that is not rolling.2) When an isolated system has reached maximum entropy, such as the ice in a glass having melted completely.Work is using force to move something, so anything that doesn't use any force or move anything is not work.
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.
If you push a box forward and the box moves forward you have done how much work?
You have only done as much external work on the box as the distance it moves: work = force x distance. If it does not budge no work is done on the object. You have done "internal" work on your muscles which converts to heat energy, but technically speaking, no external work is done on the object
