1. The problem statement, all variables and given/known data The largest turtle ever caught in the US had a mass of over 800 kg. Supoose this turtle were raised 5.45 m onto the deck of the research ship. If it takes 4.60 x 10^4 J of work to lift the turtle this distance at a constant velocity, what is the turtle's weight? 2. Relevant equations 3. The attempt at a solution Weight's measured in N. so what formula would you use? Δ(KE) = 1/2 mv^2?
