1. Refer to figure 1. Calculate the rotational velocity (magnitude and direction), frequency, period, tangential velocity, centripetal force and angular momentum. radius Figure 1: Radius of rotation is 0.500 m, the ball has a mass of 0.230 kg, and spins at 120 rpm. 2. Refer to figure 2. A 25.0 kg mass rotates 0.250 m from a rotating point with an angular velocity of 30.0 rad/sec. What is its moment of inertia? What is the initial angular momentum of the rotating mass? If the radius were to extend to 0.500 m, what would be the new angular velocity? Axis
