Tarzan 95 kg is perched on a cliff 14.0 m above Jane.

Part A: What is the value of Tarzan's speed (vT) just as he gets down to Jane's level?

Part B: If Tarzan is actually moving at 10.5 m/s, what fraction (%-loss) of kinetic energy did he lose due to air resistance?

Part C: If Tarzan's mass were 40% greater, how would that affect the answer for Part A? His speed would be...

40% less
20% less
exactly the same
20% more
40% more
