1) Tarzan is running at top speed (6.0m/s) and grabs a vine hanging vertically from a tall tree.
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.
