Question

A turntable is spinning on a frictionless axle when a ball of putty is dropped onto it from above. The putty sticks to the turntable when it lands. Is angular momentum conserved for the turntable and putty (the system) during this process?

Answer 1

Yes

Step-by-step explanation:

Gravity and forces form the axle (external forces) do not cause forces that tend to cause rotation around the turntable's axle.
