QuoteTwo friends of mine don't believe that two falling human bodies don't always fall at the same rate.
They don't believe me that jumpers fall at different rates.
Help!
Two jumpers - identical twins with matching equipment. One has a normally opened parachute, and the other has a baglock.
Do you think they will have the same terminal velocity upon landing/arrival?
Why or why not?

QuoteThey still think they're right and I'm wrong. They both took physics in school and I didn't so they use that against me. Thanks for the help though. I tell them there's one sure way for me to prove it to them, thats to come up to the DZ and try it. Thats not going to happen so I guess I'll have to live with being wrong in there eyes.
Wow, they must not have paid very much attention in those physics classes. Did they pass the course? I took physics in high school and college and it was very clear to me before I ever made a skydive that they are wrong. But whuffos will be whuffos. They're always more qualified to talk about skydiving than we are. Didn't you know that? (They teach 'em that in physics, you musta missed it)
LMAO at the whuffos.

The formula for calculation terminal velocity is:
Vt = sqrt( 2W/(Cd * rho * A))
Vt = terminal velocity in feet/second
W = weight in pounds
Cd = drag coefficient - assume 0.75
rho = atmospheric density (about 0.0024 at sea level)
A = surface area in square feet
So, it's pretty clear that if weight and/or surface area between two objects is different, the terminal velocity will be different. Tell them to go back to physics class and look up Newton.
