How do I find the rotational velocity of the disk

[From: ] [author: ] [Date: 12-02-22] [Hit: ]
PLEASE HELP.sqrt( f/(r*m) ) = v/r = 10.......
A horizontal force of 210 N is exerted on a 2.0 kg disk as it rotates uniformly in a horizontal circle of radius .9 meters. Calculate the speed of the disk.. PLEASE HELP.

-
centripetal force = m*v^2/r

rotational velocity = v/r

f/r = m(v/r)^2

sqrt( f/(r*m) ) = v/r = 10.801 rad/s
