Find the weight of a body moving upward with an acceleration of 2m / s ^ 2, if its mass at rest is 20kg.

Initial data: a (acceleration with which the body moves up) = 2 m / s ^ 2; m (body weight at rest) = 20 kg.

Reference values: g (acceleration due to gravity) = 10 m / s ^ 2.

When the body moves upward along an arbitrary vertical line, its weight can be calculated by the formula: P = m * (g + a).

Let’s calculate: P = 20 * (10 + 2) = 240 N.

Answer: The body weight when moving up will be 240 N.
