A 1 kg can of paint fell from the roof of a 5 m high house. Fall time 1 s. In this case, the average power of gravity is …

To find the power of gravity when a can falls from the roof, we use the formula: N = A / t = F * S / t = m * g * h / t.

Constants and variables: m – the mass of the fallen paint can (m = 1 kg); g – acceleration due to gravity (g ≈ 10 m / s2); h is the height of the roof of the house (h = 5 m); t – time of the can falling (t = 1 s).

Let’s calculate: N = m * g * h / t = 1 * 10 * 5/1 = 50 W.

Answer: B. The power of gravity is 50 watts.
