Homework Help: Physics

Posted by Tsukuyo on Wednesday, November 25, 2009 at 9:54pm.

a) Imagine you are swinging on a vine, like a pendulum. If the coefficient of friction between your hands and the vine is 0.5, what must your grip strength be compared to your weight to not slip?

b) Research on grip strength shows that males have an average strength of 490N per hand, and females around 290N per hand, could you hang on?

c) What is the longest vine you could swing from given you gender?

d) If you began to slip along the vine (assuming a longer vine), and re-gripped further down the vine, would it become easier or more difficult to hang on?

Please show the work too, thanks.
