A bucket of water, raised to a height of h = 1.2 m, has a potential energy of P = 150 J. Determine the mass of the bucket of water.

Initial data: h (the height to which the bucket was raised) = 1.2 m; Ep (potential energy possessed by a bucket of water) = 150 J.

Reference values: g (acceleration due to gravity) ≈ 10 m / s2.

We express the mass of a bucket with water from the formula for calculating the potential energy: En = m * g * h, whence m = En / (g * h).

Calculation: h = 150 / (10 * 1.2) = 12.5 kg.

Answer: A bucket of water has a mass of 12.5 kg.
