The potential energy gained by lifting a 20 kg box 5 meters is calculated using the formula PE = mgh, where m is mass, g is acceleration due to gravity, and h is height. Plugging in the values, we get PE = 20 kg * 9.81 m/s^2 * 5 m = 981 J. So, 981 Joules of energy is required to lift a 20 kg box 5 meters.
The work done can be calculated using the formula: Work = force x distance. In this case, Work = 20 N x 5 m = 100 joules. Therefore, 100 joules of work are done when a 20 newton box is lifted 5 meters off the floor.
The work done is equal to the change in potential energy, which can be calculated as (mass x gravity x height). Plugging in the values: (200 kg x 9.8 m/s^2 x 5 m) = 9800 J. Therefore, 9800 joules of work are done when the box is lifted 5 meters above the floor.

The work done in lifting a 100 N box 3 meters off the ground is 300 Joules (100 N * 3 m = 300 J). Work is calculated as force multiplied by distance in the direction of the force.
The work done in lifting a 100 N box 3 meters off the ground is 300 Joules. This is calculated by multiplying the force applied (100 N) by the distance it is lifted (3 meters) and the cosine of the angle between the force and the direction of motion (which is 0 degrees in this case).
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 a 100 N box 3 meters off the ground is 300 Joules (100 N * 3 m = 300 J). Work is calculated as force multiplied by distance in the direction of the force.
The work done in lifting a 100 N box 3 meters off the ground is 300 Joules. This is calculated by multiplying the force applied (100 N) by the distance it is lifted (3 meters) and the cosine of the angle between the force and the direction of motion (which is 0 degrees in this case).
The work done is calculated by multiplying the force applied with the distance moved in the direction of the force. In this case, the work done would be 100 joules (20 N * 5 m).
