Calculate the linear speed due to the Earth's rotation for a person at 40° north latitude on the Earth. The radius of the Earth is 6.40 *10⁶ m. A) 74.0 m/s B) 356 m/s C) 465 m/s D) 73.0 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 7.2921 x 10^-5 rad/s) and r is the Earth's radius. Substituting the given values, v = 7.2921 x 10^-5 rad/s * 6.40 x 10^6 m * cos(40°) ≈ 356 m/s.
