loe skaters often end their performances with spin turns, where they spin very fast about their center of mass with their arms folded in and legs together. Upon ending, their arms extend outward, proclaiming their finish. Not quite as noticeably, one leg goes out as well. Suppose that the moment of inertia of a skater with arms out and one leg extended is 3,1 kg-m² and for arms and legs in is 0.90 kg m². If she starts out spinning at 5.4 rev/s, what is her angular speed (in rev/s) when her arms and one leg open outward? Express your answer in revolutions per second. VAZO + ? rev/s

A typical hard disk in a desktop computer is a uniformly solid, 400 gram disk 3.5 inches in diameter, and takes 70 milliseconds to spin from rest up to a frequency of 7200 revolutions per minute (r.p.m.). Problem 2.6. What is the moment of inertia of the disk in kgm2?Problem 2.7. Considering that work corresponds to a change in kinetic energy, how much work is done to accelerate the disk from rest to its final spinning rate?
In ice figure skating, a couple execute a“top” (see picture). The centre of mass ofthe woman (58 kg) is situated 1.3 m fromthe axis of rotation which is vertical andpasses through the centre of mass of theman (85 kg). They are spinning at aconstant angular velocity equal to ?? rad/sand the man and woman have moments ofinertia, about their own centres of mass, equal to 1.6 and 2.5 kg.m2 respectively. Then the woman grabs the neck of the man. At this point, her moment of inertia decreases to 1.4 kg.m2 and her body centre of gravity is 0.9 m from the axis of rotation. Determine the new angular velocity.Hints: This is a conservation of angular momentum problem, and needs the parallel axis theorem to determine moments of inertia about the axis of rotation. The skaters are moving as one body with one angular velocity, but they each have their own moments of inertia given relative to their own CoMs. For the man, that’s fine...the axis they’re rotating about passes through his CoM, but the…

Ice skaters often end their performances with spin turns, where they spin very fast about their center of mass with their arms folded in and legs together. Upon ending, their arms extend outward, proclaiming their finish. Not quite as noticeably, one leg goes out as well. Suppose that the moment of inertia of a skater with arms out and one leg extended is 3.2 kg ⋅ m2 and for arms and legs in is 0.80 kg ⋅ m2. If she starts out spinning at 5.0 rev/s, what is her angular speed (in rev/s) when her arms and one leg open outward?

A 4.0-m-diameter playground merry-go-round, with a moment of inertia of 400 kg ⋅ m2, is freely rotating with an angular velocity of 2.0 rad/s. Ryan, whose mass is 80 kg, runs on the ground around the outer edge of the merry-go-round in the opposite direction to its rotation.

For a classroom demonstration, a student sits on a piano stool holding a sizable mass in each hand. Initially, the studentholds his arms outstretched and spins about the axis of the stool with an angular speed of 3.72 rad>s. The moment of inertiain this case is 5.33 kg # m2. While still spinning, the student pulls his arms in to his chest, reducing the moment of inertiato 1.60 kg # m2. (a) What is the student’s angular speed now? (b) Find the initial and final angular momenta of the student.

While sunbathing on the balcony of your 3rd floor apartment, you notice someone drop a m = 6.5 kg pumpkin from rest from the roof of the 5-story building across the street. Since you just completed a course on surveying, you know that the two identical buildings are d = 29 m apart, and have floors that are h = 4.8 m tall. The first floor is at ground level, as shown. a) Determine the magnitude of the angular momentum of the pumpkin, in kgm^2/s, by you as it passes the fourth floor balcony of the other building. b) Same question but with the 3rd floor, directly across from you. c) Same question but as it passes the second floor. d) Same question but immediately before it hits the ground. I was not given the radius of the pumpkin so I need to find the magnitude of the angular momentums without r.
