# Angular position, speed, and acceleration

## 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

$$\omega$$f=$$\omega$$i+$$\alpha$$t
$$\vartheta$$f=$$\varthetai$$+$$\omega$$it+(1/2)$$\alpha$$t2

## The Attempt at a Solution

2.52x10^4=0+$$\alpha$$3.3=7636.36
$$\vartheta$$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/s2 for the first part and to find rad for the second part?
