When a 20 newton box is lifted 5 meters off of the floor how much joules does it work?

The work done is stored as potential energy of the box
P=Mgh
F=Ma (a=g)
F=Mg
h=5m
Therefore the work done is
20*5 = 100 joules

How many joules of work are done when a 20 newton box is lifted 5 meters off of the floor?

How many joules of work are done when a 20 newton is lifted 5 meters off of the floor?
The idea here is to multiply the force by the distance.
A box having a mass of 5.00 kg is lifted 75.0 cm from ground level to the top of a desk What is the gravitational potential energy of the box on the desktop. show your work?
m g h = (5.00) x (9.8) x (0.75) = 36.75 newton-meters = 36.75 joules, with respect to the floor.
A 50 newton force is required to push a 10 kg box 30 meters across the floor. The box is then lifted up 6 meters and placed on a shelf. How much total work was done?
2,088 J
How much work in joules is performed when a force of 800.0 N is exerted while pushing a crate across a level floor for a distance of 1.5 meters?
We must assume that the force pushes parallel to the floor.Work = (force) x (distance) = (800) x (1.5) = 1,200 newton-meters = 1,200 joules

What is the potential energy when a 5 kg box is lifted 3 m from the floor?
The potential energy is 147 joules.
How much work does 25-newton force do to lift a potted plant from the floor to a shelf 1.5 meters high?
If the 25N force is directed straight up, so that the force itself moves 1.5 meters tofinish the job, then it does 37.5 joules of work, which becomes 37.5 more joules ofgravitational potential energy that the plant has, once it's on the shelf.
What amount of work is done on a chair that is pushed 89 m across a floor by a horizontal 30-N net force?
Just use the basic definition of work:work = force x distanceIf the distance is in meters and the force is in newton, then the work will be in joules.
What amount of work is done on a cart that is pushed 4 meter across a floor by a horizontal 50 Newton net force?
Work= 200 Joules.
Can an object have energy when it is at rest?
Sure. When a 6-kg bowling ball is resting on a shelf that's 2 meters off the floor, it has 12 joules of gravitational potential energy referenced to the floor.
