Two cars collide head-on on a level, friction-free road. The collision was completely inelastic, and both cars quickly came to rest during the collision. The velocity of this system's center of mass is always zero.
The abrupt, violent coming together in direct contact of two bodies is known as the collision.a falling object and a floor are examples of collision.
Because there is no external force acting on the system and its end velocity is zero, the system's final linear momentum is also zero.
This means that the initial linear momentum should be zero as well, which explains why the body's center of mass is always at rest.
There is no external force, so there is no friction resistance, so when the two objects collide, the net change in one should be compensated by the net change in the other.
Which is why the change in linear momentum of the small mass object is equal to the change in momentum of the large mass object.
Two cars collide head-on on a level, friction-free road. The collision was completely inelastic, and both cars quickly came to rest during the collision. The velocity of this system's center of mass is always zero.
Hence, option B is correct.
