    Please help with the following problem. Provide step by step calculations for each problem.

    You have a mass of 59 kg and are on a 28-degree slope hanging on to a cord with a breaking strength of 224 newtons. What must be the coefficient of static friction to 2 decimal places between you and the surface for you to be saved from the fire?

    If the coefficient of static friction is zero, to the nearest tenth of a degree, what would the incline angle have to be in order for the cord not to break?

    Let us take notations:

    my mass m = 59 kg
    angle of the slope A = 28°
    the breaking tension of the cord T_{max} = 224 N
    the minimal static friction coefficient k_min = ? to be found
    free fall acceleration g = 9.8 m/s^2

    Answer to the 1st question:

    there are 4 forces acting on me:
    the force of gravity mg directed downwards, mg,
    the normal force from the ...
