SUMMARY
The correct answer to the multiple-choice question regarding the net force calculation is D, confirmed through the application of the momentum change formula. The user calculated the initial momentum (p before) as 2 kg·m/s and the final momentum (p after) as 1.2 kg·m/s, resulting in a change in momentum (Δp) of 0.8 kg·m/s. By dividing this change in momentum by the time interval (Δt) of 0.2 seconds, the net force (Fnet) was determined to be 4 N, aligning with the textbook's answer.
