You can calculate potential energy using the mgh formula: mass * gravity * height, the product of the three indicating how much work has been done. The amount of time would not be relevant - the amount of potential energy in an object that took 10 minutes to get lifted to a height of 2m is the same as if it took 5 seconds.
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 the work done to give a box 400J of energy is against gravity, it would be equal to the force required multiplied by the vertical height lifted. This means the work done would depend on the weight of the box and the distance it is lifted.
The work done by the forklift is equal to the force exerted multiplied by the distance lifted. To calculate work, we need to know the force exerted by the forklift and the distance the object is lifted. The work done is given by the formula: Work (W) = Force (F) * Distance (d).
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.
The work done lifting the tomato against gravity is calculated as the product of its weight (force due to gravity) and the vertical distance it is lifted. The weight of the tomato is 195g * 9.81 m/s² = 1.91 N. Therefore, the work done lifting the tomato is 1.91 N * 19.4 m = 37.03 Joules.

Work = force * distance Work = 23N * 2.3 meters = 53 Joules of work is done ==================
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.
work done is = to force multiply by displacement here force is = 1000x10 N and dispacement is 75m = 75x104
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.
If a 100 N box is lifted 3 meters off the ground, the answer is 300 joules.
