∙ 11y agowork done = force x distance. Your distance is 4m and your force is approximately 27.5N because weight is a force and to work out weight you do mass x gravitational field strength (approximately 9.81).
So overall you have: Work done = (2.8 x 9.81) x 4
This equals 110 Nm to 3.s.f.

Describe the effect that height has on the force and energy needed to lift an object?
Lifting an object to a greater height requires more energy, but not any more force, thanlifting it to a not-as-great height.
What does a block and tackle do?
It decreases the effort needed to lift an object.
How much force to lift 50 kilograms onto a shelf 3 meters high?
The height is irrelevant. The energy required depends on the height; the force does not. The weight of an object, and therefore the force required to lift it, is mass x gravity - about 500 Newtons.The height is irrelevant. The energy required depends on the height; the force does not.

What does the weight of the airplane have to do with the lift of it?
The weight of an aircraft counteracts the lift produced by an aircraft. The heavier an aircraft weighs the greater the lift needed to get off the ground.
How much power is needed to lift a 2000N object in 4.0s?
500N
How much force are you exerting when you lift a 50 pound dumbbell?
Any force that is more than 50 pounds will lift a 50-pound object. The greater the force is, the greater the object's upward acceleration, and the sooner the object will reach any given height.
What is the relationship between the effort and the weight of an object being lifted over a simple pulley?
the effort needed to lift an object is about the same as the weight of an object:)
Does the use of an incline plane reduce the force necessary to lift up an object?
Yes. It is easier to push an object up a plane than lift it straight up. It does not reduce the total amount of energy needed to lift it up.
Whats the relationship between the distance traveled by the object and the force needed to lift the object When one changeswhat happens to the other?

What simple machine reduces the amount of effort needed to lift a heavy object?
Lever Hoist
How much force would be needed to lift a 200-pound object with a double pulley?
25 newtons
How much work is required to lift a 4.6-kg concrete block to a height of 4.0 m?
Work (W) is the result of the multiplication of the force applied and the displacement of the object. In this case, the force is that needed to overcome the gravity that pulls the block to the earth: 4.6 kg multiplied by the gravity constant of Earth 9.80665 m/s^2, which amounts to 45.11059 N. Thus, the work needed to lift 4.6 kg at a height of 4 m is 207.508714 J.
