To calculate the work done, you can use the formula:

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

Where:

  • Work is measured in joules
  • Force is measured in newtons
  • Distance is the distance moved in meters
  • \( \theta \) is the angle between the force and the direction of motion

Since the person is lifting the bowling ball vertically upward, the angle \( \theta \) is 0 degrees, which gives us \( \cos(0) = 1 \).

Given:

  • Force = 60 newtons
  • Distance = 2 meters

Plugging in the values:

\[ \text{Work} = 60 , \text{N} \times 2 , \text{m} \times 1 \] \[ \text{Work} = 120 , \text{joules} \]

Therefore, the correct answer is:

120 joules
