Homework Help: Rope Forces

  1. Nov 18, 2007 #1
    1. The problem statement, all variables and given/known data

    How much tension must a rope withstand if it is used to accelerate a 1400 kg car vertically upward at 0.50 m/s2?

    2. Relevant equations

    Fg=mg F=ma

    3. The attempt at a solution

    So far i know Fg=13720 and the Fnet is 700 so i'm not sure but do i subtract 700 from 13720?

    Would it make sense, physically, if the tension force were less than the gravitational force, as you are saying?
