5. A solid uniform disk, laisk = MR², a thin hoop, and a solid uniform sphere, all with the samemass and radius, are free to rotate about a fixed axis through their centers. With the objectsstarting from rest, identical forces are simultaneously applied to the rims as shown. Rank theobjects according to their angular momenta after a given time t.diskhoopsphere

The torque acting on the given systems are: τd=Frτh=Frτs=FrAgain, torque in terms of angular momenta, τd=dLdtFr=dLdt⇒L =Frtτh=dLdtFr=dLdt⇒L =Frtτs=dLdtFr=dLdt⇒L =Frt Hence all are same.

A solid metal disk with moment of inertia I, radius R, and mass m1 can rotate freely about a frictionless axis passing through its center. A light string is wrapped around the disk and connects to a hanging mass m2. The hanging mass is released from rest at a distance d above the ground and accelerates downward with acceleration awhile the disk rotates through an angle q. a) Draw free body diagrams for the disk and the hanging mass. b) Find an expression for the angular accelerationaof the diskin terms of m2, I, R, and any necessary constants. c) Find an expression for the time it takes for the hanging mass to reach the ground. Write your answer in terms of q, a, and any necessary constants.
Problem 8 A person of mass m stands on the rim of a large disk of mass M and radius R. (r= R for the person) Initially the system rotates with angular velocity w around the center of the disk. Then the person starts to walk towards the center of the disk. Calculate the angular velocity of the system when the person is at 7- R/2. (Idisk = MR²/2. Treat the person as a point object, i.e. Iperson = mr²) Axis m TAR Problem 9 A rod of length L and mass M lies on the z axis between 0 and - L. The mass of the rod is non-uniformly distributed along its length in such a way that the mass density takes the form 2M L² Calculate the moment of inertia of the rod with respect to the origin, (z = 0).

Conservation of Angular Momentum An example of conservation of angular momentum is jumping on a Merry-Go-Round. Watch this video (it starts part way through but the only thing you miss is the people pushing the Merry-Go-Round) to see someone jumping on a Merry-Gr-Round in motion like this problem. You can model the Merry-Go-Round as a solid disk with a radius of 3.00 m and a mass of 75.5 kg. Initially the Merry-Go-Round has an angular velocity 7.90 radians / second. Then the person jumps on and change the Moment of Inertia of the system. The person lands on the outer edge of the Merry-Go-Round and has a mass of 60.0 kg. What is the final angular velocity of the system after the person jumps on? You can treat the person that jumps on a point mass (which means they are significantly smaller than the radius of the Merry-Go-Round) for this problem.
