A boy weighing 500N holds a weight of 120N in his hand above his head. What is the reaction force of the support acting on the boy?
Task data: Pm (boy’s weight) = 500 N; Pr (weight of the kettlebell held by the boy) = 120 N.
The reaction force of the support acting on the boy is determined by the formula: N = m * g * cosƟ = P * cos 0º = Pm + Pg.
Let’s calculate: N = 500 + 120 = 620 N.
Answer: The reaction force of the support of 620 N acts on the boy.
