The amount of work done by this person is equal to 196 Joules.

Given the following data:

  • Force = 98 Newton.
  • Mass = 20 kg.
  • Load distance = 2 meters.
  • Effort-distance = 4 meters.

To calculate the amount of work done by this person:

How to calculate work done.

Mathematically, the work done by a person is calculated by using this formula:

[tex]Work\;done = Fd[/tex]

Where:

  • F is the force.
  • d is the load-distance or displacement.

Substituting the given parameters into the formula, we have;

[tex]Work\;done = 98 \times 2[/tex]

Work done = 196 Joules.
