To convert from degrees to radians, you need to multiply by pi/180. Since one arc-second is equal to 1/3600 of a degree, the conversion factor in this case is pi/180/3600.

(x radians / second) x (1 revolution / 2 pi radians) x (60 seconds / minute)= (60x) / (2 pi) (revolution / minute)Multiply (radians per sec) by (60)/(2 pi) = 9.5493(rounded) to get RPM.
Since an entire circle is 2π radians, 1/8 would be π/4
It was 6 radians per second. Angular acceleration = -3 radians per second2 Initial angular velocity = 6 radians per second. Final angular velocity = zero. Average angular velocity = 3 radians per second. Angular displacement in 2 seconds = 3 x 2 = 6 radians.
1.57 radians.
The angular velocity of a pulley turning 1800 rpm is 60 pi radians per second.
