Answer:
7.40m/s
Explanation:
The masses of the cars with their respective initial velocities are;
Since the two car stuck after collision, they all move with a common velocity in the same direction.
Let the velocity at which the two cars will be moving after collision be V.
From the conservation of momentum, in a closed system, momentum before collision is equal to momentum after collision.
Mathematically,
By substitution, we obtain;
Dividing through by 408, we obtain
Therefore,v=7.40m/s
