What do you think? Per the forum rules, you must show that you've put some effort into the problem before getting help.

As per the instructions, try converting the $3 \pi \ \mathrm{\frac{rad}{sec}}$ to more common, everyday units. Then do a google search. See what you come up with.

I apologize, I’m new to the forum but this is what I’ve gotten so far, I am not able to identify an object that has an RPMof 90.

Okay, good so far.

Type in "90 rpm" into google search, and see what hits you get.
