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
rotational velocity = v/r
f/r = m(v/r)^2
sqrt( f/(r*m) ) = v/r = 10.801 rad/s
