another good suggestion by teacher

[color=blue][b]Good idea, I try  no promises, I need to figure out the computational physics of this, in relation to what is already made.[/b][/color]

“possible to make "explosion" case?

Before "explosion", one single mass to be keyed in (either moving or stationary)
After "explosion", 2 masses flying apart (students to key in ratio?)
Quantities to be calculated are final velocities, initial and final KE, initial and final momentum.
