Please help me answer the following problem:

Problem 2 The Earth makes one full rotation about its axis in approximately 24 hours, or 86,400 s. It rotates at a Constant rate, and its angular speed is @ = $6400 21 - 7.27 x 10 5 rad/s. The Earth's radius is 6.38x10" m. Be sure to show all work. (a): 8 points What is the magnitude of the angular acceleration a of the Earth, in rad/s??(b): 8 points What is the magnitude of the centripetal acceleration of an object sitting on Earth's equator, in m/s??(c): 8 points Los Angeles does not lie on the Earth's equator. Is the magnitude of the centripetal acceleration of an object in Los Angeles greater than, less than, or equal to that of an object on the equator? Justify your answer.{d}: 8 points Draw a. free-Izmzmzlg,r diagram of an object sitting on the Earth's equator. Include the net force vector in your diagram. It's the direction of your venture that mute, net the length
