With what force do you need to act on a body weighing 1 kg to lift it to a height of 2 meters in 1 second?

To find the applied force when lifting a given body, we use Newton’s second law: F = m * a = m * 2 * h / t ^ 2.

Values of variables: m – mass of the lifted body (m = 1 kg); h – lifting height (h = 2 m); t is the duration of the rise (t = 1 s).

Let’s make a calculation: F = m * 2 * h / t2 = 1 * 2 * 2/1 ^ 2 = 4 N.

Answer: The body being lifted must be acted upon with a force of 4 N.
