Math Problem Statement
A 49.1 kg wagon is towed up a hill inclined at 17.8◦ with respect to the horizontal. The tow rope is parallel to the incline and has a tension of 158 N in it. Assume that the wagon starts from rest at the bottom of the hill, and neglect friction. The acceleration of gravity is 9.8 m/s^2 How fast is the wagon going after moving 54.5 m up the hill? Answer in units of m/s.
