Thank you for posting your question here at brainly. Below is the answer:
m = 80 kg R = 6.4 x 10^6 m Earth completes one rotation in 24 hours Thus, T = 24 x 3600 s Centripetral acceleration is given by ac = w^2R ac = (2 pie/T)^2R ac = (2 pie/T)^2R = 4 pie^2/(24 x 3600)^2 x 6.4 x 10^6 ac = 0.034 m/s^2
