First post, so be nice :P(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

A box with mas of 20kg is hanging from a rope on a building site. Calculate tension when:

a) Stationary

b)Moving upwards at consteant speed of 6m/s

c)Moving upwards with accelleration of 6m/s

2. Relevant equations

f=ma

3. The attempt at a solution

I don't know as i have never seen 'tension' used in a question before but i am guessing that for a) you take acceleration as -9.8m/s2 (gravity) and work out force. for b) same as a and c) is -9.8+6 and then into equation.

I am quite new to this (as you can tell) and got confused with tension. I am currently taking tension as the quivilent of force.Am i right? (P.S: I could use 9.8 as acceleration if i wanted positive answer).
