A baseball bat is rotating at 350rpm(revolutions per minute) at contact. What is the angular velocity in radians per second?
You've posted a dozen or so similar questions all under different names.
Are you really feeling that schizophrenic this evening?

To convert the angular velocity from revolutions per minute (rpm) to radians per second, you need to use conversion factors.
First, let's define the given variables:
- Angular velocity in rpm: 350 rpm
To convert rpm to radians per second, follow these steps:
Step 1: Convert revolutions to radians
One revolution is equal to 2π radians.
Therefore, to convert from revolutions to radians, multiply by 2π:
350 rpm * 2π radians/1 revolution = 700π radians/ minute
Step 2: Convert minutes to seconds
To convert from minutes to seconds, multiply by 60:
700π radians/minute * 60 seconds/1 minute = 42000π radians/second
So, the angular velocity of the baseball bat at contact is 42000π radians/second.
