A 23 kg box hangs from a rope. What is the tension in the rope if the following are true? a)The box is at rest? b)The box moves up at a steady 5.0 m/s? c)The box has Vy = 5.0 m/s and is speeding up at 5.0 m/s^2? d)The box has Vy = 5.0 m/s and is slowing down at 5.0 m/s^2 I have gotten a) = 225.4N. Because acceleration is 0. I do not know how to go about solving the other three parts though. I know the force of gravity is acting on the box in addition to the tension force. For b): Since velocity is constant, I would think that the forces would be in equilibrium. But apparently I am wrong. I really have no idea how to solve this. Any help at all would be appreciated.
