Earth has a radius of 6300 km. It makes a rotation every 24 hours. (a) What is the angular speed (w) of Earth in rad/s? (b) What is the speed of a point on the equator of Earth as it makes this rotation?
Added by Nerea Q.
Step 1
Given that t = 24 hours = 24 * 60 * 60 seconds = 86400 seconds Therefore, w = 2π / 86400 = 2.31 x 10^-5 π rad/s Show more…

(a) What is the angular speed ω about the polar axis of a point on Earth's surface at a latitude of 33° N? (Earth rotates about that axis.) (b) What is the linear speed v of the point? What are (c) ω and (d) v for a point at the equator? (Note: Earth radius equals 6370 km and let one day be 24 hours)
