ahhh okay! thank you! would that just be my answer?

ohh okay thank you. I think I got the terminal velocity...but I'm having trouble finding the height the marble needs to be dropped from the moon. What velocity should I use?

F=-kv and k= 0.1854

okay. thank you.

no, since they ask for the velocity in one part of the problem...

oh wait! sorry i misunderstood the problem! k is the constant of proportionality for the DRAG. so air resistance. but it still doesn't change does it?

no they dont. they just say at height 'H'.

ahhh. sorry what i said about hookes law. for falling objects, it stays constant since it is the acceleration. is this correct?

hmmm. but in the example they use falling objects...not springs. that's what I'm stuck on.

yea that was what i was wondering...no it doesn't say that. maybe the velocity is the same right when they are released? the only possible reason i can think of...

hookes law.

yes.

Homework Statement Does height affect the constant of proportionality? 'k' Homework Equations no relevant equations The Attempt at a Solution I don't think it does but I'm not sure why though.

Homework Statement How do you find the height where two same marbles have the same velocity when one marble is dropped from the Earths atmosphere (g=9.8) and the other is dropped from the Moons atmosphere (g=1.6)? Both are dropped from the same height Homework Equations kinematic...
