Question

1. A person lifts a suitcase of mass 15 kg from the
ground to the top of the bus. If height of bus is
2 m, does the person do any work? If yes, calculate
the amount of work and if not, why?​

Answer 1

Answer:

Yes, there was some work done.

m = 15 kg

g = 10 m/s^2

h = 2 m

Work = Mass x Gravity x Height

         = 15  x 10  x 2

          = 300 J.

hope this helps you! :)
