A crate is lifted vertically 1.5 m and then held at rest. The crate has weight 100 N (i.e., it is reese (enr647) – HS OnRamps 04: Intro to Work and Energy – mcdaniel – (34472020) 2 supported by an upward force of 100 N). How much work is being done to hold the crate 1.5 m above the ground in this way?

Answer:150Joules

Explanation:

Work is said to be done if a force is applied to cause a body to move through a distance.

Work done = Force × distance

Given force = 100N

Distance = 1.5m

Work done = 100 × 1.5

Work done = 150Joules.

The amount of work done to hold the crate 1.5 m above the ground is 150 J.

To calculate the amount of work done to hold the crate 1.5 m above the ground, we use the formula below.

Formula:

  • E = Wh................ Equation  1

Where:

  • E = Work required to lift the crate above the ground
  • W = Weight of the crate
  • h = vertical height of the crate above the ground.

From the question,

Given:

  • W = 100 N
  • h = 1.5 m

Substitute the given values into equation 1

  • E = 100(1.5)
  • E = 150 J.

Hence, the amount of work done to hold the crate 1.5 m above the ground is 150 J.
