(I) Jane, looking for Tarzan, is running at top speed (5.0 m/s) and grabs a vine hanging vertically from a tall tree in the jungle. How high can she swing upward? Does the length of the vine affect your answer?
Homework Answers
Velocity of the girl (v) = 5 m/s.
Let the length of the vine = l .
We set the P.E. = 0 at the ground.
As the tension in the vine does no work, energy is conserved.
the length of the vine does not affect the height - it affects the angle.

Tarzan, in one tree, sights Jane in another tree. He grabs the end of a vine with length 20 m that makes an angle of 45 with the vertical, steps off his tree limb, and swings down and then up to Jane's open arms. When he arrives, his vine makes an angle of 30 with the vertical. Calculate Tarzan's speed just before he reaches Jane. You can ignore air resistance and the mass of the vine.
