2. A wheel is rotating at an angular velocity of 1.2 pi radians/s while a point on the circunference of the wheel travels at 9.6 pi m in 10 seconds.
a) How many revolutions does the wheel make in 1 min?
thank you so very much! Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! A wheel is rotating at an angular velocity of 1.2 pi radians/second
while a point on the circumference of the wheel travels at 9.6 pi m in 10 seconds.
a) How many revolutions does the wheel make in 1 min?
----
60[1.2 pi rad/sec] = 72 pi rad/min
[72 pi rad/min] * [ 1 rev/2 pi] = 36 revolutions per minute
