A planet similar to the Earth has a radius 7.1 x 10° m and has an acceleration of grav- ity of 10 m/s on the planet's surface. The planet rotates about its axis with a period of 25 h. Imagine that the rotational speed can be increased. If an object at the equator is to have zero apparent weight, what is the new period? Answer in units of h. of r cell the plas the 07 ( By what factor would the speed of the object be increased when the planet is rotating at the higher speed? Why
