Question

A 96 N sack of grain is hoisted to a storage
room 52 m above the ground floor of a grain
elevator.
How much work was required?

Answer 1

Work required = \(\sf Force \times distance\)

Here force will be the gravitational force (96N) and distance is given 52m.

Answer 2

thank you , do you know how to find potential energy at that height ?

Answer 3

Yes, basically the potential energy stored at that height = work done
