First, the circumference of an 18 inch wheel is 18 * pi = 56.549 inches.
80 miles per hour is 80 * 5280 * 12 = 5069000 inches per hour. This is 5069000 / 3600 = 1408.06 inches per second.
So, 1408.06/56.549 = 24.90 rev per second.

What is Revolutions per minute in CNC?
are a measure of angular velocity whereas metres per minute are a measure of linear velocity.
How do you find angular velocity in radians per second?
-- Determine the number of revolutions, vibrations, reciprocations, or full oscillations in one second. -- Multiply that number by (2 pi).
How do you convert radians per second to meters per second?
the tangential velocity is equal to the angular velocity multiplied by the radius the tangential velocity is equal to the angular velocity multiplied by the radius
Solution and answer of angular velocity?
It is the rate of change - with respect to time - of the angular displacement.
What is the angular momentum of the 2.6 kg 5.6 cm diameter rotating disk.?
Without knowing the angular speed, i.e. RPM or some such velocity, it is not possible to answer the question. Please restate the question, giving all of the required information.
What is the physical significance of angular velocity?
Angular velocity means how fast something is turning around. Often measured in radians per second, or revolutions per minute.
What is Revolutions per minute in CNC?
are a measure of angular velocity whereas metres per minute are a measure of linear velocity.
Define constant angular velocity and explain how it is applies to a CD?
Angular velocity is the measure of angular displacement (in one or the opposite) direction over a unit period of time. In the context of CDs , one unit in which this can be measured is the number of revolutions per second. A constant angular velocity means that the CD is turning through the same angle each second.
What is angular momentum?
Angular momentum is an expression of an objects mass and rotational speed. Momentem is the velocity of an object times its mass, or how fast something is moving times how much it weighs. Therefore angular momentum is the objects mass times the angular velocity where angular velocity is how fast something is rotating expressed in terms like revolutions per minute or radians per second or degrees per second.

What is the dimension of angular velocity?
The dimension of angular velocity is reciprocal time . . . 1/time or T-1 . It'll be stated as "some angle" per "unit of time", like "45 revolutions per minute", and angles are dimensionless.
What is the difference between angular velocity and angular momentum?
angular momentum and angular velocity
Relation between linear velocity and angular velocity?
linear velocity= radius* angular velocity
Can uniform angular velocity has acceleration?
No, uniform angular velocity means no angular acceleration.
What is Difference between angular velocity and angular speed?
Angular velocity is a vector with a direction and angular speed is a scalar with no direction.
Is angular displacement and angular velocity the same?
no, velocity=displacement/time
What is the formula for the angular velocity?
There are several, what is it that you want to calculate? The "natural" units for angular velocity are radians/second. The relationship between linear velocity and angular velocity is especially simple in this case: linear velocity (at the edge) = angular velocity x radius.
