When a person tries to lift a heavy box but is unable to move it, no work is done on the box because work is only done when there is displacement in the direction of the force. It's possible that the person expended energy in trying to lift the box due to muscle contractions, but if the box doesn't move, no work is done on it.
The work done to lift the box is given by the formula: work = force x distance. Plugging in the values with force = 10.0 N and distance = 0.9 m, the work done would be 9.0 Joules.
The work done to lift the box can be calculated using the formula: work = force x distance. The force required would be equal to the weight of the box, which is the mass of the box multiplied by gravity (9.8 m/s^2). The distance is given as 0.5 meters. Calculate the force needed to lift the box (mass x gravity), then multiply it by the distance to get the work done in Joules.
The work done to lift the box is given by the formula: work = force x distance. In this case, the force is 20 N and the distance is 2 m, so the work done is 20 N x 2 m = 40 J.
The work done to lift the 5-kg box to a height of 1 meter would be 49.05 Joules (work = force × distance). In this case, the force required to lift the box against gravity can be calculated as force = mass × gravity, which is force = 5 kg × 9.81 m/s^2.

The work done to lift the box to a height of 1 m can be calculated using the formula: work = force x distance. In this case, the force required to lift the box against gravity is equal to its weight, which is 30 kg * 9.8 m/s^2 (acceleration due to gravity). The distance is 1 m. Therefore, the work done is 294 joules.
Negative work is being done when you push on a box but it moves backwards. This means that the force you apply is in the opposite direction of the displacement of the box, resulting in a decrease in its energy.
The work done to slide the box up the inclined plane can be calculated by multiplying the force required to push the box (275N) by the distance the box is being moved (3m). Therefore, the work done is 825 Joules.

No work is being done. Work is when an object moves in the same direction as the force applied to it.
The work done to lift the box is given by the formula: work = force x distance. The force here is the weight of the box, which is the mass (30 kg) times the gravitational acceleration (9.8 m/s^2), equal to 294 N. The distance lifted is 1 m. Therefore, the work done to lift the box is 294 J.
An example of doing work is lifting a box from the ground to a shelf. In this scenario, work is being done against gravity to move the box vertically.
