700 x 4 = 2,800 newton-meters = 2,800 joules

1000 m in a KM Kilo means 1000 so kilometer is 1000 meters :)
work = f x s. work = 1000 x 40 40000J
The work done on the fallen tree would depend on the force applied, not just the distance lifted. Work is calculated as force multiplied by distance. Without knowing the force applied, we cannot determine the work done.

If a 100 N box is lifted 3 meters off the ground, the answer is 300 joules.
If a 100 N box is lifted 3 meters off the ground, the answer is 300 joules.
The work done in lifting the tree is equal to the force applied multiplied by the distance it is lifted. The amount of work done would depend on the weight of the tree and the force required to lift it to a height of 2.75 meters above the ground.
If a 100 N box is lifted 3 meters off the ground, the answer is 300 joules.
700 x 4 = 2,800 newton-meters = 2,800 joules
The work done is 2 joules. Work is calculated by multiplying the force exerted (1 newton) by the distance moved in the direction of the force (2 meters).
Work = force * distance Work = 23N * 2.3 meters = 53 Joules of work is done ==================
78*6*9.8 N = 4586.4 N
