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?

  • math -

    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.
