3) During a laboratory experiment involving circular motion, a 0.150 kg object whirls in a
horizontal circle of radius 0.055 m. The frequency of rotation is determined to be 600
revolutions per minute. Determine the magnitude of the

a.) centripetal acceleration (answer is 220 m/s^2

b.) net force acting on the object (answer is 33N)

Studying for my test tomorrow but I’m not sure what formulas to use for this question.
