find w (omega) for a spoke on a bike revolving 120 times per minute?

[kukky]

i really dont understand how to do this any help

 

[Sprity]

i assume dat w is angular velocity
w=2pi/time
=2pi/60sec*120
=4pi
=4*3.14
=12.56rad/sec

 

[Dennis]

w = radians / second

2pi radians is 1 revolution

so 120 rev/min=120*(2pi)/60 = 4pi radians / second

 

[como]

ω = 120 x 2 π radians / min

ω = 240 π radians / min

ω = 754 radians / min
