You are playing with a 75 g yo-yo that has diameter 56 mm. The string is 1.2 m long. You throw the yo-yo down at 10 cm/s. When it hist the bottom of its motion you flick your wrist to make it "sleep", meaning is just spins in place. Assuming no friction, what is the angular velocity of the yo-yo in rad/s as it sleeps
