To move a refrigerator of mass 170 kg into a house, a mover puts it on a dolly and covers the steps leading into the house with
Arte-miy333 [17]

Explanation:

The given data is as follows.

         mass (m) = 170 kg,        Distance (s) = 9.6 m

        Height (h) = 3.3 m,         Force (F) = 1400 N

First, we will calculate the work performed by her as follows.

                W = Fs

                    = 1400 N \times 9.6 m

                    = 13440 J

Hence, minimal work necessary to lift the refrigerator is as follows.

               U = mgh

                   = 170 kg \times 9.8 \times 3.3 m

                   = 5497.8 J

Therefore, we can conclude that he performed 5497.8 J of work.
