The machine lifts a body weighing 1 kg to a height of 1 m in 1 s. Find the power of the car.

Machine power can be calculated using the formula:
P = A / t, where A is the useful work performed by the machine, t is the operating time of the machine (t = 1 s).
Useful work:
A = Ft * h, where Ft is the acting gravity (Ft = m * g, m is the body mass (m = 1 kg), g is the acceleration of gravity (we take g = 10 m / s ^ 2)), h is the height to which the body was lifted (h = 1 m).
Let’s calculate the power of the machine:
P = A / t = m * g * h / t = 1 * 10 * 1/1 = 10 W.
Answer: The power of the machine is 10 W.
