Apotter's wheel moves uniformly from rest to an angular speed of 0.20 rev/s in 32.0 s. (a) find its angular acceleration in radians per second per second. rad/s2 (b) would doubling the angular acceleration during the given period have doubled final angular speed?

a. The wheel accelerates uniformly, so its constant acceleration is equal to the average acceleration:

b. Yes. Since

then multiplying by 2 means we double the change in angular speed, but the wheel starts from rest so only the final angular speed gets doubled.

i'm on my way to history not a mistory.
