Calculate the linear speed due to the Earth's rotation for a person at a point on its surface located at 40° 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 a latitude θ is given by v = ω * r * cos(θ), where ω is the angular speed of Earth's rotation (approximately 7.27 × 10^-5 rad/s) and r is the Earth's radius. At 40° N, v = 7.27 × 10^-5 * 6.40 × 10^6 * cos(40°) ≈ 357 m/s.
