Homework Help Overview

The problem involves a pole vaulter falling from a height and landing on a foam rubber pad, with a focus on calculating the velocity just before impact and the force exerted during the collision. The subject area includes concepts of kinematics and dynamics in physics.

Discussion Character

  • Exploratory, Assumption checking, Conceptual clarification

Approaches and Questions Raised

  • Participants discuss the need for attempts or questions to facilitate learning. One participant expresses a lack of understanding of physics and mentions specific equations related to momentum and motion. Others question the understanding of the forces involved in the fall and the meaning of the equations provided.

Discussion Status

The discussion is ongoing, with participants encouraging the original poster to engage more actively with the problem. There is a focus on clarifying fundamental concepts and the relevance of the equations mentioned, but no consensus or resolution has been reached yet.

Contextual Notes

There is an indication that the original poster may not have a foundational understanding of physics, which could impact their ability to approach the problem effectively. The discussion highlights the importance of attempting to solve the problem rather than seeking direct answers.

a 59 kg pole vaulter falls from rest from a height of 4.7 m onto a foam rubber pad. the pole vaulter comes to rest 0.34 seconds after landing on the pad. calculate the athlete's velocity just before reaching the pad. calculate the constant force exerted on the pole vaulter due to the collision. (the answers are: -9.6 m/s, 1666 N)

you've got to post some form of attempt or at the very least a question..
we aren't going to just give you the answer, you won't learn anything from that

what about this problem do you not understand?
have you started to attempt to solve it, if so how far have you gotten?
 


i literally know nothing about physics. apparently I'm supposed to use the following:
delta p=Ft
mv=Ft
z=1/2at^2

That'll be a bit of bother then.. how come you are doing physics problems if you know nothing of physics?


Regarding the first part of the problem, do you know what it is that makes the pole vaulter fall to the ground? If so, do you know how to relate that to the equations you have?
Furthermore, do you understand what the equations you have mean?
