How do you calculate inelastic collisions?
Given perfect inelasticity, we go back to first principles.
For inelastic collisions momentum is conserved, but energy is lost. Hence, recall,
To demonstrate, I will do a problem.
Two asteroids strike head-on: before the collision, asteroid A (
Now, recall what we talked about!
is the velocity of the compound asteroid after the collision (in the positive direction).
