Solution to problem 13.7.1 from the collection of Kepe O.?. consists in determining the modulus of the Coriolis force of inertia of a locomotive, which moves along rails laid along the equator from east to west at a speed of 20 m/s. The angular velocity of the Earth is 0.0000729 rad/s. The locomotive is considered a material point.
To solve the problem, you need to use the formula for calculating the Coriolis force:
Fк = 2mvΩsinφ,
where Fk is the Coriolis force, m is the mass of the locomotive, v is its speed, Ω is the angular velocity of the Earth’s rotation, φ is the latitude of the place where the locomotive is located.
Since the locomotive moves along the equator, then φ = 0. Substituting the known values into the formula, we get:
Fk = 2 * 8 * 10^4 * 20 * 0.0000729 * sin(0) ≈ 233 N.
Thus, the modulus of the Coriolis force of inertia of the locomotive is equal to 233 N. The answer is obtained accurate to the integer part.
