Answer the bonus question in full solution and details

Usual picture: Rohting Pictue "Towards the centre" a-0, so Fact =0 E- Fn Lac Frety pM-ac Centripetal force = centripetal acceleration + Newton's 2nd Law my=F Negative because it's down towards the centre of Earth Fn= MCg-a), The centripetal acceleration takes away from the acceleration due to gravity. Intuitition: 'g' will lower due to spinning because the ground itself is accelerating away Bonus: How short would a day have to be for 'g' to be zero at the equator?
