rad/s^2

This is how i did this, but its wrong:

(1.8/0.6)=3

then, (0.6-0)/3=0.2 , so the answer

should be 0.2 rad/s^2, but its wrong I don't understand why!

**Damon**, Friday, March 23, 2012 at 6:07pmv final = v initial + a t

.6 revs/s = a t

average speed during acceleration = .6/2 = .3 revs/s

1.8 revs = .3 revs/s * t

t = 6 seconds

a t = .6 revs/s

a = .6/6 = .1 revs/s^2

but 1 rev = 2 pi radians

a = .1 revs/s^2 * 2 pi radians/rev =

.2 pi radians/s^2

= .628 radians/s^2
