SUMMARY
The mass of the man is calculated using the principle of conservation of momentum, specifically the equation p1 = p2. In this scenario, the man throws a ball weighing 250 grams at a speed of 8.0 m/s, resulting in a backward movement of the man at 0.05 m/s. The calculations confirm that the man's mass is 40 kg, derived from the equation 250 g * 8 m/s = m2 * 0.05 m/s.
