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.
