Homework Statement
Sorry this may be a better picture. I missed the top of the page but the question says
1) In the pole vault event, an athlete runs as fast as possible towards the bar, holding a flexible fiberglass pole. He stick s the end of the pole into a slot in the ground, swings up on the pole and over the bar as shown below (not to scale). Assume the athlete has a mass of 60 kg and his center of mass is 1 m high, relative to the ground. Could you tell me if my steps to part d are correct.
GPE initial - Wfinal = GPEfinal
-Wfinal = GPE final - GPE initial
- 3.5F = 588J - 2646 J
-3.5F = -2058J
F = 588N
My updated answers for question 1 are
1 B) 9.52m/s
1 C) 513 w
