Thank you for the opportunity to help you with your question!

Centripetal acceleration = v² / r 

v = √ar = √(9.76)(3.87 x 10^6) = 6146 m/s 

= 22125 km/h = 13748 mph.....................................................

Please let me know if you need any clarification. I'm always happy to answer your questions.
