A car of mass 200kg moving with 3m/s collide with another car of mass 300kg moving in the same direction at 2m/s they collide and together after that what is the common velocity
Answers
Mass of the first car (m_1) = 200 kg
Velocity of first car (v_1) = 3 m/s
Mass of the second car (m_2) = 300 kg
Velocity of the second car (v_2) = 2 m/s
Initial momentum = 2 × 300 + 200 × 3 = 1200 kg m/s
Now, let the common velocity after the collision be v.
Final momentum = (200 + 300) × v
Since, the forces during the collision are internal forces. Hence, the momentum of the system will be constant.
500 v = 1200
v = 2.4 m/s
Hence, the common velocity after the collision will be 2.4 m/s
