Tarzan is 12 m up in a tree when he decides to return to ground level....

Tarzan is 12 m up in a tree when he decides to return to ground level. Instead of climbing down, he grabs a vine and swings down. Tarzan has a mass of 80 kg. Use work and energy wherever possible to recieve full credit.

a. What is Tarzan's speed when he reaches the ground? Assume air resistance can be ignored.

b. Tarzan discovers that he has swung in the wrong direction and is over a lake when he reaches ground level. So he decides to "barefoot water ski" to shore. if the water exerts a resistive (friction like) force of 600 N, how far across the water will he travel before coming to a stop?

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.
