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.
