To what height should a 10 kg weight be lifted so that it has an energy of 200 J?

Initial data: m (mass of the weight to be lifted) = 10 kg; En (potential energy that the weight should have) = 200 J.

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

We express the height to which the weight must be raised from the formula for calculating the potential energy: En = m * g * h and h = En / (m * g).

Calculation: h = 200 / (10 * 10) = 2 m.

Answer: The kettlebell needs to be raised 2 meters.
