SUMMARY
The discussion focuses on interpreting a momentum graph to determine the object's momentum at 3 seconds, which is exerting a force of 35 Newtons. The participant initially calculated the momentum as 105 kg·m/s but received a mark indicating the answer was incorrect. The correct approach involves calculating the area under the graph between t=1 and t=3 seconds, which consists of a rectangle and a triangle, to accurately determine the change in momentum.
