Two bodies of masses 5 kg and 3 kg are moving towards each other at velocities of 3 m/s and 5 m/s, respectively. What is the velocity of their centre of mass?

Two bodies of masses 5 kg and 3 kg are moving towards each other at velocities of 3 m/s and 5 m/s, respectively. What is the velocity of their centre of mass? Correct Answer The centre of mass is stationary

The velocity of the centre of mass = (m1*v1 + m2*v2)/(m1 + m2) m1 = 5kg m2 =3 kg v1 = 3 m/s v2 = -5 m/s [opposite direction) Velocity of centre of mass = (5*3 – 3*5)/(5+3) = 0.
