Answer :
Final answer:
The work done by the potter in lifting the luggage is 220 J.
Explanation:
To calculate the work done, we need to use the formula:
Work = Force × Distance × cos(θ)
In this case, the force is the weight of the luggage, which is 15 kg × 9.8 m/s² = 147 N. The distance is the height the luggage was lifted, which is 1.5 m. The angle θ is 0° since the force is applied vertically.
Using the formula, we can calculate the work as follows:
Work = 147 N × 1.5 m × cos(0°)
cos(0°) = 1, so the work done is:
Work = 147 N × 1.5 m × 1 = 220 J.
Therefore, the correct answer is 220 J (b).
