To calculate the work done when lifting an object, you can use the formula:

\[ \text{Work} = \text{Force} \times \text{Distance} \times \cos(\theta) \]

In this case:

  • The force (weight of the box) is 50 newtons.
  • The distance lifted is 0.5 meters.
  • The angle \( \theta \) is 0 degrees because the force and the movement are in the same direction (upward).

Since \(\cos(0) = 1\), the formula simplifies to:

\[ \text{Work} = 50 , \text{N} \times 0.5 , \text{m} \times 1 = 25 , \text{joules} \]

Therefore, the work done by the person is 25 joules.
