AP EAMCET · PHYSICS · Center of Mass Momentum and Collision
A particle of mass \(10 \mathrm{~g}\) is moving towards east with a velocity of \(10 \mathrm{~ms}^{-1}\) and another particle of mass \(15 \mathrm{~g}\) is moving towards north with a velocity of \(5 \mathrm{~ms}^{-1}\). The magnitude of the velocity of the centre of mass of the system of the two particles is
- A \(5 \mathrm{~ms}^{-1}\)
- B \(10 \mathrm{~ms}^{-1}\)
- C \(15 \mathrm{~ms}^{-1}\)
- D \(7.5 \mathrm{~ms}^{-1}\)
