That's interesting and very straight forward spelled out, thanks, kuruman. That's one less thing for me to get tripped up on at some point in the future, which is always a good thing. :smile:
I see, that's good imagery and easy to follow. When a ball reverses, it will have 0 velocity (and 0 speed, if it was thrown straight up, otherwise it would be a function of trajectory). So if I’m not mistaken, I’m looking to solve for time when velocity=0.
In the case of your example...
Thanks again. :smile:
I very much appreciate all of your tips (and can't emphasize that enough.) I was actually hoping to get some feedback referencing variables without wanting to overly-bombard you for assistance.
However there is something else I'd like to check if you don't mind.
A...
Awesome, thanks. :smile:
The initial reference that you made to 'any time t':
x(t)=x0+v0t+(1/2)at2
so replacing (t) with (tm) would be:
X1(tm) = x0+v0t+(1/2)at2
X2(tm) = x0+v0t+(1/2)at2
and as you noted,
X1(tm)=X2(tm), then
x0+v0t+(1/2)at2 = x0+v0t+(1/2)at2 (I'm not sure how to properly...
Thanks so much kuruman for getting me started on this. Here goes:
Object 1:
x0 = 0 (if time is "0", it hasn't gone anywhere thus position would be "0")
v0 = 7f/s
a = -.25f/s
t = unknown
Object 2:
x0 = 80
v0 = 4f/s
a = -.45f/s
t = unknown
Therefore (if this is correct) the equations for...
Homework Statement
Two projectiles, projected at the same time with the following attributes:
Object 1: Traveling 7 feet/per sec, accelerating -.25 feet/per sec
Object 2: Starting projected position is 80 feet ahead of object 1, traveling 4 feet/per sec, accelerating -.45 feet/per sec.
How...
