Find the weight of a body moving upward with an acceleration of 2m / s2, if its mass at rest is 20kg.

These tasks: a (acceleration of a given body) = 2 m / s2 (the body’s acceleration vector is directed upward); m (mass of a given body at rest) = 20 kg.

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

The weight of a given body with uniformly accelerated upward movement is determined by the formula: P = m * (g + a).

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

Answer: The weight of the given body will be equal to 240 N.
