Simple Question, Where am I going wrong!!?! The Question: A computer is reading data from a rotating CD-ROM. At a point that is 0.0251 m from the center of the disk, the centripetal acceleration is 250 m/s2. What is the centripetal acceleration at a point that is 0.0856 m from the center of the disc? My Work: To find V Ac = V^2/r 250 m/s^2 = V^2/.0251 V^2 = 6.275 V = 2.50499501 To Find Ac with the new radius: Ac = 2.50499501^2/.0856 Ac = 73.30607477 m/s^2 <------------ This solution is wrong, is there anything wrong with my calculations?
