Also, a year on the planet lasts 89.7 days. Calculate the average angular s of the planet about its own axis of rotation in radians per second. with the second as measured on Ea rad s Calculate the average angular speed of the planet as it travels around its neighboring star, with the socond as measured on Earth rad s In other words, for the purposes of unit conversion there are 24 hours in a day, 60 minutes io an hour, and 60 seconds in a minute, as it would for astronomers on Earth observing the planet. Previous check Ansaer NextExplanation / Answer
angular speed = angle rotated/time interval
angular speed = 2pi/(52.1*60*60)
angular speed = 3.35*10^-5 rad/s <<<<<-----answer
---------------------
angular speed = angle rotated/time interval
time interval = 89.7 Earth days = 89.7*24*60*60 = 7750080 s
angular speed = 2pi/7750080 = 8.1*10^-7 rad/s <<<<<-----answer
