1) Tarzan is running at top speed (6.0m/s) and grabs a vine hanging vertically from a tall tree.(adsbygoogle = window.adsbygoogle || []).push({});

a) How high can we swing upward?

b) Does the length of the vine affect the answer?

Ok, where do I start. Don't you need the mass to solve this kind of problem??

2) In the high jump, the KE of an athlete is transformed into gravitational potential energy without the aid of a pole. With what minimum speed must the athlete leave the ground inorder to lift his center of mass 2.10m and cross the bar with a speed of 0.80 m/s?

Don't understand. period.
