Answer 2

The answer is zero.

• From the question, we get to know that the person of 1.5 m height is holding a 20 Kg trunk and is just standing at the bus terminal.
• There is no movement of the person from one place to another which means there is no work done.
• No displacement = no work done.
• Therefore the work done is zero.
