Answer 1

angular speed per second?

Answer 2

welll i had to change it to radians

Answer 3

you are given the number of revolutions per minute.
Each revolution around the fan is 360\({\color{black}{ ^{\circ} }}\)..
So, 950 revolutions would be: 342000\({\color{black}{ ^{\circ} }}\)

this is: 342000\({\color{black}{ ^{\circ} }}\)/min
if you want per second, then divide the number of degrees by 60 (since 1min=60 sec)

and that comes out to be:
5700\({\color{black}{ ^{\circ} }}\)/sec.

want to c hange to radiasns?
then:
950\({\color{blak}{ {\pi} }}\)/min
or
15\({\color{back}{ \large{\frac{5}{6}} }}\) \({\color{black}{ {\pi} }}\)/sec
