We know the heart shaped object has a moment of inertia of I =
0.5kgm^2. Calculate the change in angular momentum (L) of the
object in 5s (~L=~τ∆t). This question deals with angular momentum
conservation. Two girls of mass 100 kg each stand at the center of
a rotating merry-go-round (MGR) in the shape of a disk of radius 1
m and mass 10 kg. The platform rotates atω= 0.40 rad/s. Let’s call
this configuration instant A.

A disk with moment of inertia 9.15 × 10−3 kg∙m^2 initially rotates about its center at angular velocity 5.32 rad/s. A non-rotating ring with moment of inertia 4.86 × 10−3 kg∙m^2 right above the disk’s center is suddenly dropped onto the disk. Finally, the two objects rotate at the same angular velocity ?? about the same axis. There is no external torque acting on the system during the collision. Please compute the system’s quantities below. 1. Initial angular momentum ??...
