Homework Statement
An empty elevator of mass 2.7x10 (3) kg is pulled upward by a cable at an acceleration of 1.2 m/s (2)
a) What is the tension in the cable?
b) What would be the tension in the cable if it was accelerating downward at 1.2 m/s (2)?
c) What would be the tension in the cable if it was moving with a constant velocity of 0.50m/s?
Homework Equations
So far as I know,
F=m x a
The Attempt at a Solution
I am pretty new to physics and I've been doing alright so far but these elevator tension questions are killing me. I actually have no idea where to go. When I worked it out (probably not right) I found the cable to have more tension in the downwards acceleration rather than upwards. I'm pretty sure I'm wrong I just need someone more experienced to tell me so. I would be really greatful for any help! Thanks!
