Question

A biologist inspects an owl's nest that is built in a hollow cavity of a tree. Refer to the image. The mass of the biologist is 54.0 kg. The rope makes an angle of θ = 37.0^o with the vertical. Her legs are pushing out against the tree at an angle of ϕ = 19.5^o above the horizontal.

(a)

What is tension in rope? N

(b)

What must be the minimum coefficient of static friction μ_k to keep her shoes from slipping down the trunk of the tree?
