SUMMARY
The discussion centers on calculating the force required to stop a 6 kg object moving at a constant speed of 10 m/s over a period of 30 seconds. The user applied Newton's second law, concluding that the force exerted by the man is 2 N, derived from the equation F = m*v(0)/t. An alternative method suggested is the impulse-momentum theorem, which may simplify the calculation process. The solution is confirmed to be correct, but the importance of including units in calculations is emphasized.
