TS EAMCET · Physics · Center of Mass Momentum and Collision
Three particles \(A, B\) and \(C\) of masses \(m, 2 m\) and \(3 m\) are moving towards north, south and east respectively. If the velocities of the particles \(A, B\) and \(C\) are \(6 \mathrm{~ms}^{-1}, 12 \mathrm{~ms}^{-1}\) and \(8 \mathrm{~ms}^{-1}\) respectively, then the velocity of the centre of mass of the system of particles is
- A \(7 \mathrm{~ms}^{-1}\)
- B \(5 \mathrm{~ms}^{-1}\)
