What is the magnitude of the centripetal acceleration of an object on earth's equator owing to the rotation of earth? (b) what would the period of rotation of earth have to be for objects on the equator to have a centripetal acceleration with a magnitude of 9.80 m/s2?

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
