Two objects of masses `200g` and `500g` have velocities of `10i m//s` and `(3i + 5j) m//s` respectively. The velocity of their centre of mass is

`5i - 25 j`

`5/7 i - 25j `

`5 i + 25/7 j `

`25 i - 5/7 j `

Text Solution

Verified by Experts

The correct Answer is:

`bar(v)_(cm) = (m_(1)bar(v)_(1)+m_(2)bar(v)_(2))/(m_(1)+m_(2))`
