Homework Statement
You come to a river and you see a vine you will use to swing across. Your mass is 75.0 kg, the vine is 18.0 m long, and the vine breaks when under 655 N of tension.
a) at what angle from the vertical will the vine break?
b) what should be the maximum tension supported by the vine for you to safely cross the river?
Homework Equations
T=mgcosθ+ m (v^2/r)
θ=cos^-1((T-m(v^2/r))/mg)
Tmax=mgcos(0)+m(v^2bottom/r)
Tmax=mg+m(v^2bottom/r)
The Attempt at a Solution
How i would solve this problem is by using the formulas like, θ=cos^-1(T/mg)
θ=cos^-1(655/((75.0kg)(9.8m/s^2))
and get θ=27.0 degrees
and Tmax=mg
Tmax=(75.0kg)(9.8m/s^2)
=735 N
is this the correct approach?
