These tasks: h (height of the person on the stairs above the zero level) = 1.5 m; Ep (potential energy) = 900 J.

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

We determine the mass of a person on the stairs using the formula: Ep = m * g * h and m = Ep / (g * h).

Let’s make a calculation: m = 900 / (10 * 1.5) = 60 kg.

Answer: The mass of a person standing on a ladder is 60 kg.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
