The acceleration of a different speck of dust is 40 m/s.

Since the radius is been given as double and angular velocity will be constant, we can calculate the centripetal acceleration as

a = (2r)ω²

If we substitute the given values of r= 2r , and ω²= 20m/s.

Then we have

a= (2*20) = 40 m/s^2

Therefore, acceleration of a different speck of dust is 40 m/s.

<h3>What is centripetal acceleration?</h3>

centripetal acceleration can be regarded as  acceleration of a body that is traversing a circular path.

Tumutukoy ito sa kainitan, katuyuan, kalamigan, kabasaan, katahimikan, pagka-maaraw, pagkamahangin, o pagiging maulan sa isang pook, sa isang takdang oras, na maaaring magbago. Nararamdaman, naririnig, nakikita ng tao ang epekto ng panahon at maging ang pagbabago sa kalagayan nito. Nasusukat din ang panahon sa pamamagitan ng mga termometro, barometro, barograpo, sikrometro o higrometro, panukat ng hangin, anemometro, at mga panukat ng ulan. Depende rin ang taya ng panahon sa pagdating ng kapanahunan ng tag-init, taglamig, taglagas, tagsibol at tag-ulan.[1]
