M1*V1 + M2*V2 = M1*V3 + M2*V4.
0.16*1.2 + 0.16*0 = 0.16*0.6 + 0.16*V4. V4 = ?.
A 0.16 kg billiard ball moving at 1.20 m/s collides elastically with one of the same mass
at rest. It continues at a speed of 0.6 m/s afterward in a different direction from before.
What is the final speed of the other billiard ball?
I thought it was 0.6 m/s but it says I am wrong.
