Baron Munchausen claimed that he could fly on the core. Once he said that having descended from a height of 80 m to a height of 60 m, his speed increased by 20 m / s. Could the baron’s statement be true?

Data: h0 (the initial height at which Baron Munchausen was) = 80 m; h (the height to which the baron sank) = 60 m; ΔV (increase in flight speed of Munchausen at the core) = 20 m / s.

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

In order for the baron’s statement to be true, the condition must be met: ΔEp = ΔEk and m * g * (h – h0) = 0.5 * m * V ^ 2.

g * (h – h0) = 0.5 * V ^ 2.

10 * (80 – 60) = 0.5 * 20 ^ 2.

200 = 200.

Answer: The statement of Baron Munchausen could be true.
