$($a$)$

A large rotating turntable uniformly increases in angular speed from rest to $0\mathrm{.}230$ rev$/$s in $33\mathrm{.}0$ s$.$ What is its angular acceleration in radians per second per second?

rad$/$s$2$

$($b$)$

The same turntable again starts from rest and accelerates uniformly in the same time interval, but now the angular acceleration is double that found in part $($a$).$ What is true about the final angular speed?

It is double the value given in part $($a$).$It is half the value given in part $($a$).$ It is the same as the value given in part $($a$).$It is quadruple the value given in part $($a$).$
