To determine how much faster than its present speed the Earth should rotate so that bodies lying on the equator may fly off into space, we need to analyze the forces acting on an object at the equator. ### Step-by-Step Solution: 1. **Understanding the Forces**: At the equator, an object experiences two forces: gravitational force (downward) and centrifugal force (outward due to rotation). For an object to fly off into space, the centrifugal force must equal the gravitational force. 2. **Centrifugal Force**: ...
