1. The problem statement: A 5.00 x 10^2 kg object is attached by a rope through a pulley to a paddle-wheel shaft that is placed in a well-insulated tank holding 25.0 kg of water. The object is allowed to fall, causing the paddle wheel to rotate, churining the water. If the object falls a verticle distance of 1.00 x 10^2 m at constant speed, what is the temperature change of the water? (specific heat = 4186 J/kg and gravity = 9.81 m/s^2). 2. Relevant equations: Heat Lost = Heat Gained Mm Cm (Ti-Tf) = Mw Cw (Tf-Ti) 3. The attempt at a solution The instructor has not lectured on this type of problem but has asked us to read the text and give it a shot. I can't seem to find a way forward with this problem. Is this a calorimetry problem? If so, I don't understand why the distance the object fell and the fact that it fell at a constant speed is important. Any help will be appreciated...thanks in advance!
