English: Ejs open source java applet 1D collision carts Elastic and Inelastic Collision. Example (m1 = 4kg, u1 = 5m/s, m2 = 4kg, u2=0m/s) of collision carts in perfectly inelastic collision showing the equations of momentum conserved and kinetic energy associated with some energy loss.

This example (m1 = 4kg, u1 = 5m/s, m2 = 4kg, u2=0m/s) of collision carts in perfectly inelastic collision, notice the center of mass of the the masses m1 and m2 is at the location of vcm = 2.5m/s always throughout the motion.
