A brave child decides to grab onto an already spinning merry‑go‑round. The child is initially at rest and has a mass of 36.5 kg. The child grabs and clings to a bar that is 1.65 m from the center of the merry‑go‑round, causing the angular velocity of the merry‑go‑round to abruptly drop from 47.0 rpm to 19.0 rpm. What is the moment of inertia of the merry‑go‑round with respect to its central axis?

You are working on a design for a new art installation at the Bo Bartlett Hall at CSU's downtown campus, and your specialty is kinetic art. For the latest installation, you need a solid spinning disk. The disk you have has a mass of mass 15 kg and diameter 2.8 m is rotating at 2.4 rad/s. What is the magnitude of its' angular momentum if it spins about its center? 35 kg m²/s 18 kg m²/s 53 kg m²/s 70 kg m²/s
The dung beetle is known as one of the strongest animals for its size, often forming balls of dung up to 10 times their own mass and rolling them to locations where they can be buried and stored as food. A typical dung ball formed by the species K. nigroaeneus has a radius of 1.80 cm and is rolled by the beetle at 6.15 cm/s. HINT (a) What is the rolling ball's angular speed (in rad/s)? rad/s (b) How many full revolutions are required if the beetle rolls the ball a distance of 2.40 m? rev
A 3.00-kg mass is placed at (2.00, 3.00) m, and a 4.50-kg mass is placed at (2.00, -3.00) m. What is the moment of inertia of this system of masses about the x-axis? (Take the rotational axis to be on the x-axis) 15 kg m² O 67.5 kg*m² O 30 kg*m² O 0kg*m² O97.5 kg*m²
A 33.2 kg boy and a 22.0 kg girl are standing at the edge of a 161 kg merry-go-round of radius 1.41 m that is currently rotating at 32.0 rpm. The two kids then walk inward toward the center of the merry-go-round; while the boy reaches the center, the girl stops halfway. Given their new positions, what is the new rate of rotation of the merry-go-round (in rpm)? For simplicity's sake, you may treat the kids as point masses and the merry-go-round as a flat disk. Hint: Figure 10.12 in the textbook provides a good refresher on the various moments of inertia!
A 42.7 kg person starts at the center of a frictionless rotating merry-go-round that has a radius of 2.72 m and a mass of 60.5 kg that is uniformly distributed throughout. If the initial angular velocity is 5.39 rad/s, what is the tangential velocity of the person when they move to the edge of the merry-go-round?
Gerrard, a 32.0 kg boy, would like to play a merrygo-round (weighs 150 kg, 2.60 m in diameter) at a park. He initiates to push the merry-go-round until it spins at 21.0 rpm. He then follows the motion of the merry-go-round (in the same direction) as it rotates by running around (tangential) at 5.00 m/s, only to decide to jump on its platform’s outer edge.Assuming the merry-go-round is a solid disk, whatis its angular velocity just after Gerrard jumps on?
A playground merry-go-round, with radius 1.5 m and moment of inertia 72 kg m2, rotates with an angular speed 2.3 rad/s. A boy (mass 34 kg), initially at rest, hops onto the outer edge of the merry-go round. What is the new angular speed (in rad/s) just after the boy has jumped on?
