Homework Help: Tension problem

  1. Oct 4, 2007 #1
    1. The problem statement, all variables and given/known data
    Tension on the rope to pull a 1000kg mass up at 1m/s^2

    2. Relevant equations
    F=ma

    3. The attempt at a solution
    I'm not sure. It's either
    A. T=ma
    T=1000(1)=1000 N

    or
    B. T-mg=ma
    T-(1000)(10)=(1000)(1)
    T=11000N

    Thanks.

    What is Newton's 2nd law telling you?

    That the acceleration of an object is directly related to force and inversely related to mass. Basically F=ma I guess.

    directly related to what force?

    Net force. I think it's option B that I did in my first post.
