Answer:

Old man carry heavy luggage. We have to find work is done by the old man.

Explanation:

a)

Zero work is done by the old man because displacement of the body is zero.

b)

Work done , W = F.s

                     W = Fscosθ

                      W=Fscos(0°)

                      W = Fs

c)

Saurabh asked to old man because he is carrying heavy luggage and finding him uncomfortable.
