Well the purchase of the radar gun is part of what I was trying to avoid - plus I rather like doing experiments in mechanics with only the tools that Newton would have had to work with (give or take the fact that my stopwatch is digital.) But I suspect that I could rig up a bit of a sighting...
Aha. Got it now. Thanks.
You've been so helpful I might be so bold as to ask the question that got me started on the projectile/air resistance problem in the first place, because I'm not having much luck on my own. I have a water rocket whose behaviour I'm trying to explain with no more...
Ah excellent; I'm not going mad then. Thanks for your help.
Nifty Latex equation thing, let me see if I can manage it; should the following:
really read:
ma_y=mg-b|v_y|v_y?
Or is it correct that the unvectored velocity (if you'll pardon me for making up a term) should get worked...
Hello All,
I was recently intrigued by the site: http://www.lcse.umn.edu/specs/labs/catapult/ which sets about showing a computational solution to the problem of projectile motion with air resistance. I think the site is a great idea, and presented well, but it seems like some of the physics...
