Calculate the linear speed due to the Earth's rotation for a person at a point on its surface located at 40 $\degree$ N latitude.The radius of the Earth is 6.40 ´ 10⁶ m. A)299 m/s B)357 m/s C)390 m/s D)465 m/s

Question

Quizplus · Accepted Answer

The linear speed v at latitude θ is given by v = ω * r * cos(θ), where ω is the angular speed of Earth's rotation (approximately 7.2921159 × 10^-5 rad/s), r is the Earth's radius, and θ is the latitude. Substituting the values, v = 7.2921159 × 10^-5 * 6.40 × 10^6 * cos(40°) ≈ 357 m/s.
