## Homework Statement

A yo-yo has a moment of inertia of 75.0 g-cm2 about its rotation axis. What is the constant torque required to make it spin to 300 rev/min in one second, starting from rest?

## Homework Equations

∑

## The Attempt at a Solution

I was thinking since the question is asking for constant torque, angular acceleration would also have to be constant. Therefore, I would just find angular acceleration (using (ω(t) - ω0)/(t

_{2}-t

_{1})) then multiply that angular acceleration by the moment of inertia. Is that correct thinking?
