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 M R radius 13MR2 (a) Particle Figure 2

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 radius 1-MR (a) Particle Figure 2 3. Refer to figure 3. An 6.00 kg object rotates about a point 0.600 m away at 120.0 rpm. What is its angular velocity and frequency? What is its moment of inertia? What is its angular momentum? If it took 3.00 s to change its angular velocity from rest, what would be the torque (i.e. rotational force) needed to change its angular momentum? Axis M. radius 7-MR" (a) Particle Flgure 3
