When lifting the load to a height of 2 m, work was performed by 1600 J. What is the mass of the lifted body?
| February 17, 2021 | education
To find the value of the mass of the lifted load, we apply the formula: A = ΔEp = m * g * h and m = A / (g * h).
Values of constants and variables: A – work done when lifting a load (A = 1600 J); g – acceleration due to gravity (g ≈ 10 m / s2); h – height (h = 2 m).
Calculation: m = A / (g * h) = 1600 / (10 * 2) = 80 kg.
Answer: The cargo has a mass of 80 kg.
