What potential energy does a raindrop weighing 200 mg at a height of 2m have?
| April 3, 2021 | education
To find out the potential energy that a given raindrop should have, consider the formula: Ep = mk * g * h, where mk is the mass of a given raindrop (mk = 200 mg; in SI mk = 0.0002 kg); g – acceleration due to gravity (g ≈ 10 m / s2, const); h – drop height (h = 2 m).
Let’s perform the calculation: Ep = mk * g * h = 0.0002 * 10-3 * 10 * 2 = 0.004 J.
Answer: The potential energy of a given raindrop should be 4 mJ.
