| What is the weight of a body weighing m = 2 kg with accelerated upward movement with acceleration a = 2 m / s2? Under the influence of what forces does the body move?
Task data: m (mass of a body moving accelerated upwards) = 2 kg; a (constant acceleration) = 2 m / s2.
Reference values: g (acceleration due to gravity) ≈ 10 m / s2.
1) The acting forces: m * a = F (force imparting acceleration; driving force) = N (normal reaction) – Ft (gravity).
2) Weight of a moving body: P = m * (a + g) = 2 * (2 + 10) = 24 N.
Answer: A body accelerating upward has a weight of 24 N.
