Two billiard balls of equal mass undergo a perfectly elastic head-on collision. If one ball's initial speed was 1.50 m/s, and the other's was 3.40 m/s in the opposite direction, what will be their velocities after the collision? Enter your answers numerically separated by a comma. Enter positive value if the direction of the velocity is the same as the direction of the initial velocity of the first ball, and negative value if the direction of the velocity is opposite to the direction of the initial velocity of the first ball. 11.12 ΑΣΦ| m/s
