The mass of the Earth is estimated to be 5.97 x 1024 kg. Assume the Earth is orbiting the sun in a perfect
circle (it is not actually), and the radius of the circle is 1.5 x 10¹¹ m. How much is the Earth's centripetal
acceleration? (Hint: If the Earth takes 365.25 days to complete a circle around the sun, what is its orbiting
speed?)
