a.) As Earth rotates on its axis, objects at the equator experience a slightly different value of g due to additional centripetal acceleration. Calculate this adjusted value for g.

b.) Is this difference due to centripetal forces present at the poles? If g is dependent upon the position on the surface of Earth, why do we use the standard value of 9.80 m/s^2 in our calculations? Explain.

c.) Whats the value of g on board a space shuttle in a stable orbit at a height of 350 km above the equator? Hint: You don't need to know the mass of the space shuttle.

a,b I will be happy to critique your thinking. YOu know velocity at the equator...r*2PI/24hrs
