According to law of conservation of momentum the momentum in all the direction is conserved, considering the along the "i" direction we can write:
Now, consider the momentum conservation along the "j" direction:
Therefore, the velocity of the vehicles after the collsion is:
By substituting the correspondingvalues, we get the velocity of the vehciles after the collision as:
After the collision the cinetic energy of the both vehicles combined will be utilized to do work against the dricion force (given
Now, according to work energy theorem the we can write:
Where "d" is the distance travelled by the wreckage after the collision. Substituting the corresponding values, we get:
Hence, the distance travelled by the wreckage after the collsion is 7.958 m.
