Tension in the string rope

  1. Feb 8, 2012 #1
    1. The problem statement, all variables and given/known data

    1) A box of mass 42kg sits on the top of a ladder. Neglecting the weight of the ladder, find the tension in the rope. Assume the rope exerts horizontal forces on the ladder at each end.

    2. Relevant equations

    m1g – T = m1a

    3. The attempt at a solution
    T = m1g - m1a
    This is the formula i know for calculating the tension
    I have mass has 42 kg. But what is the value for acceleration here? Also I dont know because i have values for h and θ in the diagram.

    I think you are missing a critical dimension, see,

    Edit, not so sure now, think everything is fine.
