I am going skydiving. If I jump from 15000 feet, what will be my speed at 1500 feet?

where are you skydiving for a start?

assuming it is Earth and assuming that acceleration due to gravity is constant (9.8) then you use v^2=u^2+2as

yes, it is very important to know if it is earth or other planet, because the acceleration due to gravity is different in different places in the universe
anonymous
  • anonymous
that's true :)

  • anonymous
yeah thanks ... I would also need to convert my distance in meters first! It will be scary fast though!!
anonymous
  • anonymous
LOL! good luck :)

well, the formula wont help

you forgot resistance from air
anonymous
  • anonymous
which keeps increasing as your velocity is increasing
anonymous
  • anonymous
some relief to hear that!
anonymous
  • anonymous
so, you got to use some extra formulas, and you got to know your surface area, and the friction index of your clothing material in relation to air
anonymous
  • anonymous
calculus wont hurt for exact calculations
anonymous
  • anonymous
well as the question does not explicitly say which model for air resistance is being used, i think it is logical to disregard air resistance unless you are a university level physicist

anyway, have fun, my friend did it a year back, while he was in Africa :) He sayed he almosed shi**d his pants.

But after landing, he was really happy.

Can I not calculate some negative acceleration due to resistance? But how would I do that?
anonymous

I also want to do skydiving, but now i am busy with some piloting stuf
anonymous
  • anonymous
it would simply decrease your overall accelaration up to a point (terminal velocity) when your velocity is constant

cool @BecomeMyFan=D !

Speed at 1500 feet will depend on your parachute. It better be open at 1500 feet!!! lol

Hopefully slow enough to survive !!

Truthfully with the parachute, you couldn't ignore air resistance. I think you would have to do this in two parts, first ignore the air resistance for the period the chute is not opened, then a new acelleration formula would be needed when chute is opened. There is a big change in acceleration when that chute pops.
