A turntable reaches an angular speed of 45.0 rpm in 2.21 s, starting from rest. Assuming the angular acceleration is constant, what is its magnitude?
Question
Solution 1
To solve this problem, we first need to convert the angular speed from revolutions per minute (rpm) to radians per second, since the standard unit of angular speed in physics is rad/s.
1 revolution is equal to 2π radians, and 1 minute is equal to 60 seconds. So, 45.0 rpm is equal to:
