SUMMARY
The change in momentum for the given scenario is calculated using the formula delta p = p(final) - p(initial). For a ball with an initial momentum of 10 kg-m/s [E] that rebounds with a momentum of 6 kg-m/s [W], the change in momentum is determined to be -4 kg-m/s. This negative value indicates a reversal in direction, confirming that momentum is a vector quantity. The calculation assumes a head-on impact without any angular considerations.
