The wave from the boat to the shore of the lake reached in 1 min. The distance between the nearest crests is 1.5 m, the impact of waves on the shore occurs in 2 s. Calculate the distance from the boat to the shore.
Initial data: t (time when the wave from the boat reaches the coast) = 1 min (60 s); λ (wavelength, distance between the nearest crests) = 1.5 m; T (wave oscillation period) = 2 s.
1) Determine the speed of propagation of waves from the boat: υ = λ / T = 1.5 / 2 = 0.75 m / s.
2) Calculate the distance from the boat to the coast: S = υ * t = 0.75 * 60 = 45 m.
Answer: The boat was at a distance of 45 meters from the coast.
