Tension problem - HELP!
For some reason, I'm getting myself all confused about this EASY problem:
A 64.0 kg box hangs from a rope. What is the tension in the rope if:
(a.) the box is at rest?
(b.) the box moves up a steady 4.90 m/s^2?
(c.) the box has Vy=5.50 m/s and is speeding up at 5.00m/s^2?
(d.) the box has Vy=5.50 m/s and is slowing down at 5.00 m/s^2?
Why have I been using the F=ma formula and getting things wrong? I'm thinking I'm totally just making things way too hard and my brain is completely frozen!
Thanks for any help!
