The problem involves calculating the average angular acceleration of a turntable that accelerates from rest to an angular speed of 45 revolutions per minute (rev/min) over a time period of 1.5 seconds. The subject area pertains to rotational motion and angular kinematics.
The discussion is ongoing, with participants providing guidance on the conversion process and questioning the assumptions made in the original poster's calculations. There is no explicit consensus yet, as different interpretations of the conversion process are being explored.
There is a noted confusion regarding the conversion of units, particularly between revolutions and radians, which is central to the problem. The original poster's approach to unit conversion is under scrutiny.

First let's convert from rev/min to rad/min:
How many radians are in 1 revolution?

BrainMan said:I first converted 45 to radians by multiplying it by pi
45(3.14152654)/180 = .79 rad
