A girl pulls her 17 kg wagon along a flat sidewalk by applying a 16 N force at 39° to the horizontal. Assume that friction is negligible and that the wagon starts from rest. (a) How much work (in J) does the girl do on the wagon in the first 1.5 s? J (b) How much instantaneous power (in W) does she exert at t = 1.5 s? W
