Homework Statement
An LP turntable must spin at 3.52 rad/s to play a record. How much torque must the motor deliver if the turntable is to reach its final angular speed in 1.7 revolutions, starting from rest? The turntable is a uniform disk of diameter 30.8 cm and mass 0.26 kg.
Homework Equations
T= I * angular acceleration(a)
The Attempt at a Solution
-converted rev to rad
- found time from avg ang vel and distance
-used that to calculate acceleration
nothings working. I have tried every possible way. Someone please work out the problem so I can understand how to do this. THANK YOU! I WILL BE SOOOO GRATEFUL. I am ready to cry!
