steel ball traveling at 6 m/s hits a stationary line of three steel balls. Which statement is true if the collision is perfectly elastic?
If the collision is perfectly elastic, the following statement is true:
The kinetic energy of the first steel ball will be transferred to the line of three steel balls, causing the first ball to bounce back with the same speed of 6 m/s and the line of three balls to start moving with a velocity equal to the velocity of the first ball before the collision.
