A 38.2 kg wagon is towed up a hill inclined at 19° with respect to the horizontal. The tow rope is parallel to the incline and exerts a force of 140 N on the wagon. Assume that the wagon starts from rest at the bottom of the hill, and disregard friction.How fast is the wagon going after moving 80.0 m up the hill?
