Answer:
[tex]approx.= 25\frac{m}{s}[/tex]
Explanation:
Centripetal acceleration (a) is defined as the square of an object's velocity (V^2) divided by the distance of the object from it's point/axis of revolution (r). So:
[tex]a=\frac{V^{2} }{r}[/tex]
which allows us to solve for the velocity:
[tex]V=\sqrt{ar}\\ Since: a=3.04g=(3.04)(9.81),r=21;\\V=\sqrt{(3.04)(9.81)(21)} =25.02...[/tex]
