Homework Help Overview

The problem involves calculating the height Tarzan reaches while swinging on a vine after jumping at a speed of 8.0 m/s. The context is rooted in concepts of conservation of energy in physics.

Discussion Character

  • Exploratory, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss using a conservation of energy equation to relate Tarzan's initial speed to his maximum height. There is a question about the meaning of variables in the equation, specifically what zf represents.

Discussion Status

The discussion is ongoing, with some participants providing equations and others seeking clarification on terminology. There is mention of additional information regarding Tarzan's mass, which may influence the calculations.

Contextual Notes

The original poster is uncertain about the specifics of the problem, as it was encountered during a test. There may be constraints related to the information provided in the question.

The question is something like this I am not sure exactly because it was on my test.

Tarzan is running at 8.0 m/s and jumps onto a vine. How high above the bottom of his swing will he go ?

Plz help i have no clue how to do this
 
Physics news on Phys.org
Put what you have into a COE equation.
0= .5mvf^2 - .5 mvi^2 + mgzf - mgzi

vf=0 at top of swing
zi=0 in my reference frame

so 0= -.5 mvi^2 + mgzf

and solve for zf.
 
um...whats zf stand for
 
What you are looking for. (How high above the bottom of his swing will he go)

You know what the others stand for right?
 
i just found out that they also gave the mass of tarzan in the question the mass is 60kg
