To calculate the work done by the person lifting the bowling ball, we can use the formula for work:
\[ \text{Work} = \text{Force} \times \text{Distance} \times \cos(\theta) \]
In this case, the angle \(\theta\) is 0 degrees since the force is applied in the same direction as the movement (up). Thus, \(\cos(0) = 1\).
Given:
- Force = 60 newtons
- Distance = 2 meters
Using the formula, we get:
\[ \text{Work} = 60 \, \text{N} \times 2 \, \text{m} \times 1 = 120 \, \text{joules} \]
The correct answer is **120 joules**.
