Your answer will likely be in radians, so you could be better off expressing the acceleration in angular velocity, ω, in radians per second.
a=V2/R
=ω2R
Since a and R are both known, you can go ahead and solve for ω.
you swing a 2.2 kg stone in a circle of radius 75 cm. At what speed should you swing it so its centripetal acceleration will be 9.8 m/s^2
a rad = V^2 / R now i know R = 75 cm what do I put for V^2
