Question

multiple choice question
two identical objects moving at the same speed travel toward each other and then crash into each other. these two objects have momenta with magnitudes that are
not equal.
impossible to compare.
almost equal.
equal.

Explanation:

Momentum is calculated as $p = mv$, where $m$ is mass and $v$ is velocity. Since the two objects are identical (same mass) and moving at the same speed (magnitude of velocity), the magnitudes of their momenta are equal as per the formula.

Answer:

D. equal
