Sarita lives on 3rd floor of building at the height of 15m. She carries her school bag weighing 5.2kg from the ground floor to her house. Find the amount of work done by her and identify the force against which she has done the work.
In the answer, why m = 5.2 kg?
mg = 5.2 kg right? Because it is given the bag 'weighs' 5.2 kg???

in some questions weight is giben in the form of mass so it is us to decide whether to take weight as mass or as a weight in terms of newton
