This seems like a simple yes, but here is my confusion.

A band snaps back faster than an object would free fall.

So even if a stretched band was 20 pounds of force, it is pulling at a higher...

How are we able to estimate the height of the jump without imputting somewhere the element of time it takes to cover the distance? It seems like there is insufficient data to figure out velocity...

As I read this it makes me realize that my direction might be wrong here.

I was thinking that a certain "time" was necessary, but now I realize that time isn't the "essential" element. Although,...

Now that is cool. Thanks alot.

Please stop me if I am dragging this post along, but this is just fascinating stuff.

If an athlete laid on their back, and "pushed" a ball into the air with...

" if you tell me the height that his center of gravity rises from the instant his toe leaves the ground I can tell you what his initial vertical velocity was at that instant."

Do you know the...

Ahh I see my flaw in the air resistance! Nice! Although greater area for friction it has less friction, per unit of volume, in proportion to it's inertia. Righty?

That's interesting you say...

This is great! I've been looking for someone who was smart in this stuff!

The larger ball, considering it was greater in surface area would be more affected by friction and would not go as high?...

Well I am considering this for the effects of a vertical jump. And I think (not considering the effects of air resistance) that they would be the same.

I guess I think that two balls projected at...

Two balls are thrown in the air. One is 10kg and the other is 100kg.

The balls are thrown from the same point, at at the same velocity.

Do both balls reach the same height in the air?
