In uniform circular motion, can $a$_c (centripetal acceleration) change the speed of an object moving in a circle? Choose the best explanation.

(II) At what rate must a cylindrical spaceship rotate (Fig. 6–32) if occupants are to experience simulated gravity of 0.70 g? Assume the spaceship’s diameter is 28 m, and give your answer as the time needed for one revolution.
