Answer:
the correct one is D
Explanation:
The velocity of the center of mass of a body is
[tex]v_{cm} = \frac{1}{M } \ \sum m_i v_i[/tex]vcm = 1 / M sum mi vi
M = [tex]\sum m_i[/tex] sum my
in this case we have two bodies
v_{cm} = [tex]\frac{1}{m1+m2} \ ( m_1v_1 +m_2v_2)[/tex]1 / m1 + m2 (m1 v1 + m² v2)
v_{cm} = [tex]\frac{m_1}{m1+m2} \ v_1 + \frac{m2}{m_1+m_2} \ v_2[/tex]
we can see that the velocity is an average between v₁ and v₂, but the exact value depends on the ratio of the masses of the bodies
when checking the answers the correct one is D
