at the lowest point of his swing, is the tension in the vine greater than, less than, or equal to the gravitational force on tarzan? assume that the vine mass is negligible.




tarzen

Because it is experiencing centripetal force and gravity.

F = m (v^2/r + g)




The tension in the vine at the lowest part of Tarzan’s swing is greater than the gravitational force on
Tarzan.

If Tarzan is at rest on the vine, just hanging, the tension in the vine is equal to the gravitational force on
Tarzan.

But when Tarzan is swinging he is in circular motion, with the center of the circle at the top end of the
vine, and the vine must provide the additional centripetal force necessary to move him in a circle.
