| January 10, 2021 | education
Task data: P (weight of the lifted body) = 40 N; h (lifting height) = 120 cm = 1.2 m.
Reference data: g (acceleration due to gravity) ≈ 10 m / s2.
The work that was done when lifting a given body is determined by the formula: A = Ft * S = P * h.
Let’s calculate: A = 40 * 1.2 = 48 J.
Answer: When lifting a given body, work of 48 J.
