A mass on the end of a 0.50 m long string is spun overhead with a velocity of 3.5 m/s. What is the angular velocity of the mass? 0.14 rad/sec 1.17 rad/sec 7.00 rad/sec 24.5 rad/sec t 9964

6. Spinning Ice Skater: A 50 kg ice skater is spinning around at 2 revolutions per second with her arms tucked in. You may consider her to be a cylinder 1.5 meters high with a radius of 15 cm. She sticks her arms straight out to slow herself down. Each of her arms is 2 kg and 75 cm long. How fast does she rotate with her arms extended?

#1. Due to the conservation of angular momentum, moving mechanical parts in a spacecraft can affect the orientation and rate of angular rotation of the craft. Let us, crudely speaking, model Voyager II as a uniform disk with a mass of 720 kg and an effective radius of 1.0 meters. What is the moment of inertia of Voyager II under these assumptions? A.720kgm^2 B.580kgm^2 C.360kgm^2 D.180kgm^2 #1-1. Suppose the spacecraft in #1 is initially not rotating as a whole, and none of its compo- nents are rotating. A data tape spool with a moment of inertia of 1.25 × 10^−4 kg m^2 begins to spin at a rate of 15.5 Rad/s. What is the angular momentum of the spacecraft as a whole? A. 3.88×10^−3 kg·m^2/s B. 1.94×10^−3 kg·m^2/s C. 9.69×10^−4 kg·m^2/s D. 0.0 kg·m^2/s # 1-3. As the result of the tape spool operation, what is the magnitude of the angular speed of the spacecraft in #1-1 as a whole? A. 0.0 Rad/s B. 5.38 × 10^−6 Rad/s  C. 1.07 × 10^−5 Rad/s D. 2.14 × 10^−5 Rad/s

pls also draw a picture/representation of the scenario described, thank you!
