The bun, wanting to eat sunflower oil from a barrel, fell into it and reached the bottom after dt = 2 s. The mass of the Kolobok is m = 200 g, its density is 1.05 times greater than the density of oil, and the resistance force when moving the Kolobok in oil is F = -bv; b = 0.1 kg/s. Estimate the height of the barrel H if it was filled to the brim.
