Acomputer is reading data from a rotating cd-rom. at a point that is 0.0130 m from the center of the disk, the centripetal acceleration is 393 m/s2. what is the centripetal acceleration at a point that is 0.0884 m from the center of the disc?

The formula relating acceleration and angular velocity is:

a = ω^2 r

where a is acceleration, ω is angular velocity and r is radius

But the angular velocity ω is constant all throughout the disk therefore:

a1 / r1 = a2 / r2

So at points:

r1 = 0.0130 m     -> a1 = 393 m/s^2

r2 = 0.0884 m     -> a2 = ?

393 / 0.0130 = a2 / 0.0884

a2 = 2,672.4 m/s^2

as technology advances, new experiments often expose problems in accepted theories. c

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
