ANGULAR ACCELARATION = 2 rad/s^2

 

A spinning disk is rotating at a rate of 2 rad/s in the counterclockwise direction as shown in the figure.

 

Find the wheel's angular velocity after 4 s.

 

Find the angle through which the wheel has turned after 4 s in radians.

 

Find the magnitude of the velocity (speed) of a point located at r = 20 cm from the center of the wheel after 4 s.

 

 

Find the magnitude of the parallel acceleration of the point in the above part.

The image depicts a simple diagram illustrating directional movement. On the left side of the image, there is a horizontal oval shape representing a flat surface. Through the center of the oval, a vertical black line is shown, indicating an axis or a pivot point. An arrow curving around the vertical line suggests rotational movement around this axis. On the right side, there are four arrows arranged in a cross to illustrate directions: "Up" is indicated by an arrow pointing upwards, "Down" by an arrow pointing downwards, "Left" by an arrow pointing to the left, and "Right" by an arrow pointing to the right. This diagram is likely used to demonstrate rotational motion around an axis, as well as basic directional concepts.
