An old rope can now only safely suspend 120 kg. When the rope is
tied to a beam, it hangs down with a vertical length of 12.0
m. Calculate the minimum time required for an 85 kg person starting
from rest to climb the entire length of the rope without breaking
it.

Answer:
it.a = f/m
a = 1176 N [down] / 85 kg
a = 13.835 m/s2
using d = vi(t) + 1/2at2
t = sqrt(1.73)
t = 1.3 s
