Two balls are approaching each other for a head on, Ask an Expert

Academics

Two balls are approaching each other for a head on collision. Ball #1 has a velocity of 9.1 m/sec and Ball #2 has a velocity of -9.4 m/sec.

1) What is the velocity of the center of mass of the two balls if they both have the same mass?

v_COM = -.15 m/sec

2) What is the velocity of the center of mass of the two balls if the mass of Ball #1 is 3 times as big as the mass of Ball #2?

v_COM = m/s

Help: This is an elastic collision. What values are conserved in elastic collisions?
