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 = (2.2 N)i + (1.1 N)j . How much work does she do on the dog if its displacement is
a) d = (.25 m ) i
b) d = (.25 m ) j
c) d = (-.50 m)i + (-.25 m ) j
My main problem is whether or not I need to combine the force or simply W = Fd. Thx for any help
