Hi all,
I haven't studied rotational physics in a long time so this may be a stupid question, but here goes. I'm trying to model the properties of a turntable (record player). Using the theories of rotational motion, is it possible to calculate the time it would take for the spinning...
Please help
When a turntable rotating at 32 1/3 rev/min is shut off, it comes to rest in 29 s.
a assuming constant angular accelerationn, find the angular acceleration.
