Calculating Angular acceleration of wheel

[AkkiJay]

Homework Statement

Calculate the angular acceleration in radians per second squared of a wheel that starts from rest and attains an angular velocity of 545 revolutions per minute in 1.00 minute. (a) What is the angular displacement in radians of the wheel during the first 0.500 min? (b) During the second 0.500min?

Homework Equations

d=T/I
v=d/t
Angular speed/time interval=angular acceleration

The Attempt at a Solution

v*t=d 545 * 1=545
(545)*(0.500min)

Thank you

What are the units for angular velocity?

What are the units for angular velocity?

...and how do you convert revolutions per minute to this unit?

...and how do you convert revolutions per minute to this unit?

That's what I'm asking the OP to do. We can't do the work for him, but point him in the right direction.

Radians per second squared i think the answer should be in...can you tell me the right formulas to use because i am not sure if these are right or not.

Nearly, that's the units for angular acceleration. Angular velocity is Rad/s.

The problem asks you to find the angular acceleration first, so do that, and we'll go from there.

Ok, I have found that answer already...Can you tell me what type of lever (what class) is testtube that we use in chemistry? 1st, 2nd, or 3rd...I am thinking 1st
