How do you convert revolution per min to rad per second?
('X' rev/minute) x (2 pi radian/rev) x (1 minute/60 sec) = 2 pi X/60 = 0.10472 Xrad/sec (rounded)
How do you convert rev per sec into rad per sec?
For starter, 1 rad/S = 0.159 rev/S
An electric fan is turned off and its angular velocity decreases uniformly from 550 rev min to 200 in rev per min time interval of length 4.50 sec Find the angular acceleration in meters per sec sq?
(550 - 200) rev per minute = -350 rev per minute / 60 sec per minute = (-35/6 rev per second) change in angular velocityAngular acceleration = (change in angular velocity) / (time for the change) =(-35/6 rev per second) x (2 pi radians per rev) / 4.5 seconds = -8.1449 radians per second2("Meters per sec sq" can't be a unit of angularacceleration, since angles can't be measured in meters.)
How many revolutions would a tire make in 45 sec if its anguar velocity were 35 rev min?
There are 60 sec in one min 35 rev/min x 45/60 = 26.25 revs
The radius of a car wheel is 15 inches How many revolutions per minute is the wheel making when the car is traveling at 60 mph?
60 mph = 88 feet/sec = (88 x 12) inches per sec = (88 x 12 x 60) in/min = 63,360 inches per minuteCircumference of the wheel = 2 pi R = 30 pi inches.RPM = (63,360) / (30 pi) = 672.27 rev per min (rounded)
