(adsbygoogle = window.adsbygoogle || []).push({}); [SOLVED] Angular motion with constant acceleration

1. The problem statement, all variables and given/known data

2. Relevant equations

[tex]\varpi[/tex]= [tex]\varpi[/tex](inital) + [tex]\alpha[/tex]t

3. The attempt at a solution

I understood part A and Part b,

What I don't understand is how to do Part C.

What I did was divide the average angular velocity with acceleration. But I don't get why or a more understanding method to do this problem
