Question

The angular momentum of a freely rotating disk around its center is Ldisk. A heavy block is tossed horizontally onto the disk from two different orientations, but with the same speed, as shown in the figure. Friction acts between the disk and the block, so that the block is brought to rest on the disk and rotates with it.

In which case is the magnitude of the final angular momentum of the disk-block system the greatest?

a) same for both

b) Case A

c) Case B

The angular momentum of a freely rotating disk around its center is Ldisk. A heavy block is tossed horizontally onto the disk
from two different orientations, but with the same speed, as shown in the figure. Friction acts between the disk and the block, so
that the block is brought to rest on the disk and rotates with it.
