A rotating wheel changes angular speed from \( 1800 \mathrm{rpm} \) to \( 3000 \mathrm{rpm} \) in \( 20 \mathrm{~s} \). What is the angular acceleration assuming to be uniform?
(1) \( 60 \pi \mathrm{rads}^{-2} \)
(2) \( 90 \mathrm{rads}^{-2} \)
(3) \( 2 \pi \mathrm{rads}^{-2} \)
(4) \( 40 \pi \mathrm{rads}^{-2} \)
