How do you cange revolution per minute to radians per second?
The rotor on a helicopter turns at an angular velocity of 320 revolutions per minute (rpm). Conver this rpm value to radians per second. (anser: 33.5 rad/s)
Yes, I have the answer but I dont know the process......HELP?!?!

1 revolution = 2 pi radian
1 minute = 60 seconds
1 rev/min * (2 pi radian / 1 revolution ) * (1 min/60s) = rad/sec
So multiply rev/min by pi/30 to get in rad/sec.

2π radians = 1 revolution 60 seconds = 1 minute So, 130π radians per second = 65(2π) rads / 1 sec = 60x65 rev / 60 sec = 3900 revolutions/minute

a revolution means 2 pai radians To convert q rad/sec we have to divide by 2pai to get rev/sec Multiply by 60 to get 60 q /2pai rev /min = 30q/pai rev/min ANS ok?
