Two cars a and b are moving towards each other on horizontal surface.the car a has mass 60 kg and moves towards the right with speed 60 m/s.the car b has mass 1000 kg and move towards the left with a speed 20m/sec.the two car collide and get stuck to each other.with what velocity will they move after collision
