Relative Motion with rotating axes example 1

The video tutorial addresses a challenging relative motion problem involving a rotating disk and a slider. It begins by setting up the problem, defining key points, and explaining the velocity equation. The tutorial then delves into analyzing the velocity of the slider relative to the rotating object and the velocity of a point on the disk relative to another point. Using trigonometry and circular motion principles, the tutorial calculates the necessary components to find the absolute velocity of the slider. The importance of direction and negative signs in the final velocity vector is also discussed.

What is the angular velocity of the disk in the problem?

• 6 radians per second

• 8 radians per second
