Suppose that Mars rotates on its axis once every 24.7 hours. The equator lies on a circle with a diameter of 4214 miles. (a) Find the angular speed of a point on its equator in radians per day (24 hours). (b) Find the linear speed of a point on the equator in miles per day. Do not round any intermediate computations, and round your answer to the nearest whole number. (a) Angular speed: (b) Linear speed: radians per day miles per day X
