Homework Help Overview

The discussion revolves around calculating the impulse experienced by a 70kg person who jumps from a height of 5m and lands on firm ground. The subject area includes concepts of mechanics and impulse-momentum theory.

Discussion Character

  • Exploratory, Conceptual clarification

Approaches and Questions Raised

  • Participants are attempting to identify the appropriate equation for impulse and its relation to momentum. Some express uncertainty about the definition of impulse and its calculation.

Discussion Status

There is an ongoing exploration of the concept of impulse, with some participants providing definitions and relationships to momentum. However, no consensus or complete solution has been reached yet.

Contextual Notes

Participants are preparing for a final exam, indicating a time constraint and a focus on understanding the underlying principles rather than solving the problem directly.

im reviewing for my final tomorrow, and there is a question that asks for the impulse experienced if a 70kg person lands on firm ground and stops after jumping from a height of 5m. what equation should i use to solve this?

Start with writing down the equation for impulse. Impulse= ?
 
i don't know the equation for impulse, that's my main problem :P
 
<br /> I = \Delta p = F\Delta t<br />

Where I is impulse, and p is momentum.

So impulse is a change in momentum, or the product of a force and the time period over which it acts.
