In an experiment of centripetal force you have a rotating mass of 500 grams, which is at 5 cm from the axis of rotation. You are spinning the platform and note that 20 revolutions take 5 seconds. Calculate:
a) Calculate the angular velocity of the rotating mass (in radians per second)
b) Calculate the linear speed of the rotating mass (in meters/second). c) If the system is stopped, how much hanging mass would be required to bring the rotating mass to the same position?
