Find the weight of a person whose mass is 50 kg at the moment the lift starts moving downward

Find the weight of a person whose mass is 50 kg at the moment the lift starts moving downward with an acceleration of 0.6 m / s2.

Task data: m (mass of a given person) = 50 kg; a (acceleration of the lift at the beginning of the movement, the vector is directed downward) = 0.6 m / s2.

Reference values: g (acceleration due to gravity) ≈ 9.8 m / s2.

The weight of a given person at the moment of the beginning of movement is found by the formula: P = m * (g – a).

Let’s calculate: P = 50 * (9.8 – 0.6) = 460 N.

Answer: The desired weight of a person at the moment of the start of movement will be 460 N.
