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
