Hello, I have become very confused after i tried to solve this question. A rope pulls a 2 kg object straight up, accelerating it from rest at 2.2 m/s^2 for 3 seconds. they want the work done by each force acting on it. Ok i found the displacement as 9.9 m up. Then i found out that the applied force does 43.56 J and that Fn does 150.678 J and gravity does 194.238 J . Then they ask for the total mechanical work done. I just added the works and got -.678 . Then they ask for the net force which is 4.4 N up and work done by the net force which is 43.56 J. I am confused about finding the net work when fg,fn, fapp are involved what am doing wrong. Also when solving other questions do i include fn and fg when the displacement is vertical? Please help and thank you. i would add more detail but i got no time to study.
