A bead is tied on one end of a stiff rope of length 1 m. With the other end of the rope as the center, the rope is rotated in such a way that the bead completes 10 revolutions per second. The centripetal acceleration of the bead is

• A. $400\pi^2$ m/s$^2$
• B. $200\pi^2$ m/s$^2$
• C. 400 m/s$^2$
• D. 200 m/s$^2$
• E. 100 m/s$^2$

Hint:

Always keep track of whether your answer needs to be in terms of $\pi$ or a numerical approximation before finalizing your choice.
