Homework Help Overview

The discussion revolves around rearranging equations to solve for velocity in a physics context, specifically related to a diver's motion and the effects of gravity.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the process of rearranging equations to isolate velocity, with one participant expressing uncertainty about specific components of the equation. Another participant raises a question about how to test the calculated equation using given parameters.

Discussion Status

The discussion includes affirmations of correctness regarding the rearrangement of equations, while also exploring methods to validate the derived equation through practical application. There appears to be a mix of confidence and uncertainty among participants.

Contextual Notes

Participants are working with specific values, including a height of 3.7 m and gravitational acceleration of 9.8 m/s², but there may be missing details about the initial equations used for rearrangement.

Hi guys

I just wanted to check if i have done this correctlly

I am trying to combine and rearrange the 2 equations to make v the subject.

Please see the attached image.

Have i got this correct?

Sure. It's just fine.
 
Brilliant

Thanks Dick

I wasnt too sure about the 2x on the right hand side then finding the square root of the total. but if its ok I am pleased with that.

Hi guys

I have calculated the following equation but i need to find a way of testing it.

the info i was given is a diver at 3.7 m height and I need to find the speed at which they enter the water of the pool. Gravity = 9.8 m s-2.

How do i go about testing the equation to see if i have the right answer?
