Two objects with masses m_(1) and m_(2) are moving along the x-axis in the positive direction with speeds v_(1) , and v_(2) , respectively, where v_(1) is less than v_(2) . The speed of the centre of mass of this system of two bodies is

Answer»

GREATER than `v_(2)`
EQUAL to `v_(1)`
equal to the average of `v_(1) and v_(2)`
greater than `v_(1)` and less than `v_(2)`

SOLUTION :`V_(CM) = (m_(1)v_(1) + m_(2)v_(2))/(m_(1) + m_(2))`.
