I cannot understand it at all please help me.
When a Coolie A lifts a load on the roof of a bus in 1 minute and another Coolie B lifts the same load on the roof of the bus in 2 minutes. How can their work done been same? I need explanation and with formula .thanks
Thank you for the opportunity to help you with your question!
work done = force applied * displacement produced
work done is independent of time
here both coolies A and B are lifting the same load and the displacement produced by both coolies are same
so the work done by both of them will be same..
because work done does not depend on time,it only depends on the force applied and the displacement produced on the body.
hope you understood..please message if you have any doubts...thank you
