Since a person, standing on the platform, remains motionless, his weight can be calculated by the formula: P = m * g; with the accelerated movement of a person up or down, the formula would already be used: P = m * (g ± a).
Constants and variables: m is the mass of the person represented (m = 48 kg); g – acceleration due to gravity (g ≈ 9.8 m / s2).
Calculation: P = m * g = 48 * 9.8 = 470.4 N.
Answer: A person on a fixed support has a weight of 470.4 N.
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.
