what's the mathematical formula explaining newton's cradle??

Question

how can i calculate the effects of newton's cradle using a mathematical formula, showing the balance of momentum and energy conservation on both sides of the equation???

Answer 1

An elastic (no kinetic energy lost) collision between two objects of equal mass requires that the velocities 'change place'. that is if Object A moving with velocity Va hits object B with velocity Vb, aftr the collision A and B will have velocities Vb and Va respectively.

If Vb = 0 you get Newton's cradle.
