A body weighing 10 kg was lifted to a height of 2 m. Determine the work of lifting the load.

Initial data: m (mass of the lifted body) = 10 kg; h (the height to which the body was raised) = 2 m.

Constants: g (acceleration due to gravity) = 10 m / s ^ 2.

Since the body was lifted vertically (cos α = 1), the work of lifting the load can be calculated by the formula: A = F * S = m * g * h.

Let’s perform the calculation: A = 10 * 10 * 2 = 200 J.

Answer: When lifting the load, we did a work of 200 J.
