a.) The rotation of the Earth around its axis, as measured on the equator

b.) The Earth moving around the Earth-Sun centre of mass. Assume the orbit is circular

c._ The Sun moving around the Earth-Sun centre of mass. Same assumption as in b.)

Work shown...

i'm so confused with centrifugal and centripetal acceleration... but this question is asking for 'centrifugal' accel.

for a.) i did a_z= (omega^2)*(x)

where omega= sqrt (G*(M+m))/(r^3))

i don't understand how measure this since it's at the equator

for b.) do i simply use the weight of the earth, earth, and distance from the Earth to the sun.. and sub in

for c>0 do i simply use the weight of the sun, earth, and distance from the Earth to the sun.. and if so what's the difference

need a lot of help here.. please help!
