A 42.9 kg wagon is towed up a hill inclined at 19.7° with respect to the horizontal. The tow rope is parallel to the incline and exerts a force of 165 N on the wagon. Assume that the wagon starts from rest at the bottom of the hill, and disregard friction. The acceleration of gravity is 9.81 m/s².
How fast is the wagon going after moving 22.5 m up the hill?
