Asked by michaela c
a car's wheel turns at 200 rpm. the radius of each wheel is 1.3 ft. to the nearest radian per minute, what is the angular velocity of a point: on the tire thread? on the hubcap .4ft from the center? right at the center?

the angular velocity is the same for all points anywhere from the axle to the tire surface.
angular velocity is radians/minute
200 rev/min * 2pi rad/rev = 400pi rad/min
Now, if you want linear velocity, that is radius * angular velocity.
