By definition, the linear velocity is given by:
Where,
w: angular speed
r: radius
We have that the radius of the wheel is
Where,
d: diameter of the wheel
substituting values:
Then, we have the following conversions:
1 revolution = 2π radians
1 minute = 60 seconds
Therefore, the angular velocity in radians per second is:
Substituting values we have:
Answer:
your linear velocity is:
a. 0.62 feet per second
Where,
w: angular speed
r: radius
We have that the radius of the wheel is
