Question
Two billiard balls roll towards each other. They each have a mass of
0,3 kg. Ball 1 is moving at v1 = 1m · s−1 to the right, while ball 2 is moving at
v2 = 0,8m · s−1 to the left. Calculate the total momentum of the system.
- 1.4 m/s
- 0.06 kgm/s
- 6.4 kg m/s
- none
The correct answer is: 0.06 kgm/s
