You find that you are not alone on this island. A large, hungry jaguar is chasing you. 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. At what angle from the vertical will the vine break? What should be the maximum tension supported by the vine for you to safely cross the river?

Solution

A.) T = mLcos(theta)
(theta)=Cos_1(T/mg)=Cos_1(655/75*18) = 60.97 degree.

B.) Logically, speaking anything below 655 N should do the trick for the safety.
