A. how fast is Tarzan moving when he reaches the ground?

B. Does your answer depend on Tarzan's mass?

C. Does your answer depend on the length of the vine?

It doesn't even give you a proper length, it only says 4.0m below the ground, how am I supposed to know how much that is?

Need help with the overall calculations and B. And C.

They also do not say if the vine was initially horizontal. This information is also needed.

They probably expect you to assume

V(bottom)^2/2 = g (20 + 4 meters)

It is not a well defined problem
