We have to find the work done by Susan in pulling the dog’s leash gently with a constant force to keep her dog from running away.

The work done by Susan is given by,

 

Where,

constant force =

displacement =

Thus,

 

      = (2.2)

     = 0.55 J

Therefore, the work done by Susan if and  is 0.55 J.
