How High Did the Pole Vaulter Jump?

AI Thread Summary
The discussion revolves around calculating the height a pole vaulter achieves based on given parameters, including mass, initial velocity, and energy lost to friction. The key equation to use is the conservation of energy formula, K1 + U1 = K2 + U2 + Wf. Participants suggest breaking down the problem into smaller steps and listing known parameters before substituting them into the equation. The initial attempt at a solution is noted to be incomplete, prompting further guidance on how to proceed. The focus remains on methodically solving for the height achieved by the vaulter.

Homework Statement



A 50 kg pole vaulter running at 9.5 m/s vaults over the bar. If the vaulter's horizontal component of velocity over the bar is 1.3 m/s, and 200 J of energy is lost due to the friction in the pole, how high did the vaulter jump?

Homework Equations


K1+U1= K2+U2+Wf


The Attempt at a Solution


1/2mvi^2= 1/2mvf^2+mgh+Wf

Okay it doesn't look like much of an attempt at a solution, haha...

List your parameters first, take it small steps at a time...
Once you've listed what known parameters you have substitute it into your relevant equation as stated at you attempt at a solution. Do that and let's work from there...

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
