Question:
To keep her dog from running away while she talks to a friend, Susan pulls gently on the dog’s leash with a constant force given by F(vector) = (2.2 N)x̂ + (1.1 N)ŷ. How much work does she do on the dog if its displacement is
(a) D(vector) = (0.25 m)x̂,
(b) D(vector) = (0.25 m)ŷ,
(c) D(vector) = (–0.50 m)x̂ + (– 0.25 m) ŷ?
