How much does a boy weighing 40 kg weigh?

To find the weight of the boy in question, we will use the formula: P = m * g.

Values of constants and variables: m – weight of the boy under consideration (m = 40 kg); g – acceleration due to gravity (g ≈ 10 m / s2).

Calculation: P = m * g = 40 * 10 = 400 N.

Answer: The weight of a boy weighing 40 kg is 400 N.
