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 F⃗  = (2.0 N )x^ + (1.5 N )y^. (A) How much work does she do on the dog if its displacement is d⃗  = (0.21 m )x^, (B) How much work does she do on the dog if its displacement is d⃗  = (0.18 m )y^, (C) How much work does she do on the dog if its displacement is d⃗  = (-0.45 m )x^ + (-0.33 m )y^?

Answer 1

Answer:- givendala F = en êt is n (@) 2= 0.21m a W=2x0.21 = 0.42 Nm (6) 2= 0.18m W1.5 X 0.18 = 0.27 Nm @d'= 60.45m)2+f0.33m) ĝ W=& x60.45)+1.5x60.33) = -0.9 -0,495 2-10395Nm
