A hydraulic lift exerts a force of 12000 N to lift a car 2 meters How much work is done on the car?
24000 joules
A forklift picks up a crate using 400 N It moves the crate 20 meters in 50 seconds How much power is used?
From the question, it's hard to tell whether the 20 meters is the vertical lift, or a horizontal transfer that occurs after the lift.If the 20 meters is the vertical lift (performed by a very large fork-lift in a shop with a very high ceiling):Energy = work = 400 N times 20 m = 8,000 Newton-meters = 8,000 joules8,000 joules in 50 seconds = 8,000 / 50 = 160 joules per second = 160 watts = about 0.214 horsepower.If the 20 meters is a horizontal ride after the lift is complete, then that part of the move consumes nominally no energy or power. No force is required to move an object perpendicular to the force of gravity. Whatever force is applied initially, to get the crate moving, is returned at the end of the 20 meters, when reverse force must be applied to the crate in order to make it stop moving.
If you want to lift a 5-kg box to a height of 1 meters how much work must be done?
98 j
If a worker pushes horizontally on a large crate with a force of 298 newtons and the crate moved 6.5 meters how much work do he do?
Work = force x distance = Newtons x meters = 1937 Joules.
You lift a 45 newton bag of mulch 1.2 meters and carry it a distance of 10 meters to the garden. How much work was done?
The amount of work done is determined by an object's force times the displacement. In this case it is 28 Newton meters, or 28 Joules.

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 when a force of 10 newtons is used to lift a boy 3 meters into the air?
The work down is 10Nx3m= 30Nm( Joules).
How much can a horned dung beetle lift?

How much work does a crane do as it lifts a 240 kilogram crate from ground level to a height of 165 meters?
420,000 j
Who much work needs to be done to lift a 500kg mass from the ground to a height of 20 meters?
work=force(distance) work=500(20) work=10000 joules
