Question

Two bumper cars move toward each other. the cars hit and bounce off of each other. the momentum before the collision will be equal to the after.

Answer 1

Explanation :

It is given that two bumper cars move toward each other. The cars hit and bounce off of each other.

The momentum before the collision will be equal to the momentum after the collision.

The law of conservation of momentum states that the momentum remains conserved if no external force is applied.

i. e.

$p_i=p_f$

$p_i$ and $p_f$ are the initial and final momentum of the system.

Answer 2

The answer is the MOMENTUM before the collision is equal to the MOMENTUM after.
