**1. Homework Statement**

An LP turntable must spin at 3.53 rad/s to play a record. How much torque must the motor deliver if the turntable is to reach its final angular speed in 1.9 revolutions, starting from rest? The turntable is a uniform disk of diameter 30.7 cm and mass 0.24 kg.

**2. Homework Equations**

T=rF

F=ma

Theda = (Angular Acceleration (t^2)) / 2

**3. The Attempt at a Solution**

I tried using the above equations but i'm not sure about finding the angular acceleration to find the the final Torque.
