if a 4-ft diameter wheel turns at 12 rad/min, what is the linear speed of a point on the wheel?

Linear Speed = Radius × Angular Speed Given the diameter of the wheel is 4 feet, the radius is half of that, which is 2 feet. The angular speed is given as 12 radians per minute. Plugging in the values: Linear Speed = 2 feet × 12 rad/min = 24 feet/min So, the linear speed of a point on the wheel is 24 feet per minute.
