Question

A coolie lifts a laggage of 30 kg from the ground and put on hus 4.0m above the ground calculate the work done by him on the luggage​

Answer 1

given
mass 30kg
height 4m
gravitational acceleration 10(apx)

so
work done against gravity = mass × gravitational acceleration× height

= 30×4×10
=1200 joule

everything is step wise it will give you full marks

Answer 2

given mass or force=30 kg
distance moved =4m
work done=force×distance moved
=30 × 4
= 120 J
