To find V2, we first need to calculate the initial momentum of the system before the collision and then use the principle of conservation of momentum to find the final velocity.

Initial momentum = m1 V1
m1 = 20 kg, V1 = 500 m/s
Initial momentum = 20 kg 500 m/s = 10000 kg*m/s

Final momentum = m2 * V2
m2 = 600 kg, V2 = final velocity

According to the principle of conservation of momentum:
Initial momentum = Final momentum
10000 kgm/s = 600 kg V2
V2 = 10000 kg*m/s / 600 kg
V2 = 16.67 m/s

Therefore, the final velocity after the collision is 16.67 m/s.
