Initial angular velocity (ω) = 0
Final angular velocity (ω') = 100 rad/sec
Time taken (t) = 10 sec.
i) Now we find angular acceleration(α) 
ω' = ω + αt
100 = 0 + α*10
α = 100/10 = 10 rad/sec² .This is the angular acceleration.
ii) Now we find angular displacement (Ф)
From  Ф = ωt+1/2αt²
on substituting we get 
Ф = 0*10 + 1/2* 10*100
Ф = 500 radians
