Measuring average power during a jump

Click For Summary

Homework Help Overview

The discussion revolves around measuring the average power exerted during a jump using a scale and a measuring tape, without the ability to jump on the scale. Participants explore how to calculate average power based on energy changes and time taken during the jump.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss measuring the height of the jump and the potential energy gained, questioning how to determine the time taken for the jump without direct measurement. Some suggest using impulse and maximum force readings from the scale, while others propose alternative methods for estimating time.

Discussion Status

The discussion is active with various approaches being explored, including the use of maximum deflection of the scale and assumptions about constant acceleration. Participants express uncertainty about the validity of certain methods and the implications of their assumptions.

Contextual Notes

Participants note constraints such as the inability to jump on the scale and the complexity of accurately measuring time during the jump. There is also mention of the varying acceleration during the jump, which complicates calculations.

Sorry to TRIPLE-post, but I'd rather bring this thread up than add to the clutter with a new one.

David, way to jump to conclusions. I'm from Israel, I am not muslim, and I am not in the least bit religious. I don't know why you chose to take such offense at my questions, and I'm sorry if I've offended you in any way.
