relative velocity rolling wheel

The video tutorial explains a relative motion problem involving a wheel rolling across a floor. The problem is to find the velocity of point A on the wheel, given the velocity of the center point O. The tutorial assumes pure roll, meaning no slipping occurs, and derives a formula for angular velocity. It then uses vector algebra and trigonometry to solve for the velocity of A, providing both magnitude and direction. The solution involves understanding the components of velocity due to translational and rotational movement, and concludes with a calculated velocity of 5.656 m/s at a 45-degree angle.

What is the significance of the right angle triangle formed by the velocities of A and O?

Calculate the magnitude of the velocity of A given that the magnitude of VO is 4 meters per second.
