1. The problem statement, all variables and given/known data a person uses a cord to pull a boat of 1000 kg along 50 meters. The cord makes a 45° angle. If the applied work to the boat is 40 N, how much work is done? Given: mass = 1000 kg displacement = 50 meters the angle = 45° applied work = 40 N 2. Relevant equations Work = Fd Weight = mg Work = Fd cos θ 3. The attempt at a solution First I converted the mass to weight: 1000 kg/ 9.81 m/s = 101.9 N Then I added that to the other force so, 101.9 N + 40.0 N = 141.9 N. *I don't know if I should add or subtract* Then I used the W = Fd cos θ equation: W = (141.9 N * 50 m)(cos 45°) = 5016.9 J Is this correct?
