Question
please help with all parts
A day on a distant planet observed orbiting a nearby star is 62.3 hours Also, a year on the planet lasts 69.3 Earth days.* Calculate the average angular speed of the planet about its own axis of rotation in radians per second, with the second as measured on Earth. Calculate the average angular speed of the planet as it travels around its neighboring star, with the second as measured on Earth. In other words for the purposes of unit conversion there are 24 hours in a day. 60 minutes in an hour, and 60 seconds in a minute. as it would for astronomers on Earth observing the planet.Explanation / Answer
A)
Planet rotates 2 %u03C0 radian in 62.3 hr =62.3x3600 sec
Angular speed around axis of rotation = 2 %u03C0 /224280 = 28x10^-6 rad/s
B)
Planet moves 2%u03C0 radian in 69.3 days =5987520 sec
Avg angular speed around the star = 2%u03C0/5987520 = 1.05 x 10^-6 rad/s
