A 44.2 kg wagon is towed up a hill inclined at 17.7 with respect to the horizontal. The tow rope is parallel to the incline and exerts a force of 154 N on the wagon. Suppose 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 87.2 m up the hill?
