A 40.0 kg wagon is towed up a hill inclined at 18.5o 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. Neglect friction for the problem.
a. Draw a free body diagram and sum forces.
b. What is the acceleration of the wagon?
c. How fast is the wagon going after moving 42.0 m up the hill?
