If in the Newton 's cradle (5 ball collision) demonstration the last three balls are stuck together with chewing gum, how fast will those three balls move out when the first ball has n speed of 2 m/s as it calculate with the four balls?Is the collision elastic? calculate the kinetic energy of the incoming ball andcalculatethe kinetic energy of thethree outgoing balls.All balls have a mass of 50 grams.
