Tarzan swinging on a vine...PLEASE HELP
starting from rest at point A, Tarzan (whose mass = 100kg) swings on a 10 m long vine, which initially makes a 60deg angle with with the vertical.
a) how much lower than the starting point A is Tarzan, when he reaches point B, the lowest part of his swing?
i got 1.34
b)how much work has Earth's gravity done on tarzan between points A and B
i got 4387.80Joules
c) how fast is tarzan moving at point B? neglect friction
> i don't understand how to approach this one
d) what is the tension in the vine when tarzan passes through point B?
> yeh don't know about this one either
