SUMMARY
The discussion focuses on calculating the change in momentum for a 3.0-kg ball dropped from a height, which strikes the ground at a velocity of 16.0 m/s and rebounds at -12.0 m/s. The change in momentum is determined using the formula p = mv, where the final momentum is calculated as p_final = m * v_final and the initial momentum as p_initial = m * v_initial. The change in momentum is thus Δp = p_final - p_initial, highlighting the significance of direction in vector quantities.
