Tension help

  1. Oct 8, 2009 #1
    1. The problem statement, all variables and given/known data

    A 1.89 kg mass is suspended from a string which is pulled upward. The mass accelerates upwards with an acceleration of 3.30 m/s2. What is the tension in the string?

    The way it works here is;

    We can't help you until you show your attempt, even if it is totally wrong.

    Thanks

    From Newton's Law

    F=ma

    where

    F is the force (N)

    m is the mass (kg)

    a is the acceleration due to gravity. On Earth it is 9.81 N/s^2

    Set up a free body diagram and sum for forces in the y direction.

    Thanks
    Matt
