AI Thread Summary
To calculate the total mass of a person with additional gear, start with the human mass, which is approximately 85.79 kg for a 175 lb individual. Add the mass of the gear, including a 200 lb pack and a 50 lb parachute, resulting in a total mass of about 335.79 kg. It's acceptable to treat all components as a single mass if they share the same velocity. Clarification on the initial formula indicates that it should involve volume rather than velocity. This approach simplifies the calculation of total mass effectively.

What I have now if the mass of a human found by this
m = density x velocity
which is 189.16lb or 85.79 kg for about 175lb person.
density = 1010 kg/m3
volume = 3ft^3
but then I thought that this guy will have about 200 extra lbs of wight and a parachute along with that. How should I go about putting that into the mass?
The bag would be about 2ft * 2ft *1ft = 4ft^3 so the
mass of the pack would be about 200lb roughly?
and the parachute would be about 50lb too.
Should I just add the human mass to the other two masses for a total mass? Or am i missing something?
Thanks

Hi MegaMan64! Welcome to PF! :wink:

Yes, if they all have the same velocity, it's easier and quicker to treat them as a single mass. :smile:

Whaaaaaaa??

That doesn't lead to the units on the following line in your post...

he meant volume! :rolleyes:
 
So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
