The drawing shows three particles that are moving with different velocities. Two of the particles have mass m, and the third has a mass 2m. The third particle has a velocity of v3 = +5.1 m/s. At the instant shown, the center of mass (cm) of the three particles is at the coordinate origin. What is the velocity vcm (magnitude and direction) of the center of mass?
1 answer
The velocity of the center of mass (vcm) is 0 m/s, since the center of mass is at the coordinate origin.
