Tension on a pullstring walker

  1. Oct 17, 2013 #1
    here is how the problem looks.

    a pullstring walker is in the middle of a string that is connected to two mountain sides. the string formes an angle of 10 degrees under the horizontal. the walker has a mass of 50 KG. find the tension of the string

    any idea how to start with this one.if i set up newton 2nd law i get FG-FT+FT= 0
    which is useless because FT will cancel out.

    when i do the geometry i get an unreasonable answer of

    cosθ= adjacent/hyp
    cos10= 50/ hyp
    hyp=50/ cos10
    hyp = 49.24 N.
    is that correct?

    i did it wrong last time. i belive this is correct. answer is reasonable this time!
