Question:
Let us say you have an object that is spinning. We will call it Object
A. That object explodes creating many more objects. We will call these Objects:
B, C, D, E, F, G, H, etc. My question is this. If you do not know the speed of
the original object, is it possible to calculate the speed of that original
object? If so what is the formula, and an example of the formula in use?
Replies:
Yes, it is possible to figure our, from the pieces, what the original motion was.
This is a complex multivariable problem applied to explosions, airplane crashes, and
other such events. It is beyond the K-12 domain that we serve, but there are
procedures (usually involving conservation of momentum and conservation of energy)
and computer modeling for analyzing these situations.
