The body was lifted up with an acceleration of 2 m / s. what is its mass if the weight is 120 N.

To find the mass of an accelerated body lifted upwards, we use the formula: P = m * (g + a), whence we express: m = P / (g + a).

Variables and constants: P – body weight during accelerated ascent (P = 120 N); g – acceleration due to gravity (g ≈ 10 m / s2); a – acceleration of the body (a = 2 m / s2).

Calculation: m = P / (g + a) = 120 / (10 + 2) = 10 kg.

Answer: The mass of an accelerated body lifted upwards is 10 kg.
