Question

earth revolving around the sun in 365 days. calculate its angular velocity in rad/s. if the average distance from the sun is 150 million kilometre, also find earth's linear velocity.​

Answer 1

We know the Earth goes round the Sun, all the way around is 2 radians (360 degrees). We also know that it takes a year (approx 365 days) which is therefore about 3.2x107 secs. Therefore = 2 / 3.2x107 = 2.0x10-7 rad/s.
