## Homework Statement

A dentist's drill starts from rest. After 3.30 s of constant angular acceleration, it turns at a rate of 2.52 multiplied by 104 rev/min.

Find the drill's angular acceleration.

Determine the angle through which the drill rotates during this period

## Homework Equations

[tex]\omega[/tex]

_{f}=[tex]\omega[/tex]

_{i}+[tex]\alpha[/tex]t

[tex]\vartheta[/tex]

_{f}=[tex]\vartheta

_{i}[/tex]+[tex]\omega[/tex]

_{i}t+(1/2)[tex]\alpha[/tex]t

^{2}

## The Attempt at a Solution

2.52x10^4=0+[tex]\alpha[/tex]3.3=7636.36

[tex]\vartheta[/tex]

_{f}=0+0+1/2=4150

I know the answers are in the wrong units so can someone tell me what to do change my rev/min into rad/s

^{2}for the first part and to find rad for the second part?
