**Educational Content: Angular Motion**A spinning disk is rotating at a rate of 4 rad/s in the counterclockwise direction, as shown in the figure. The question asks: If the disk is speeding up at a rate of 4 rad/s², what is the direction of the angular acceleration vector?**Options:**- ○ right- ○ down- ○ left- ○ up**Diagram Explanation:**The diagram includes:1. A horizontal spinning disk with an arrow indicating counterclockwise rotation.2. A coordinate compass to the right, marking directions as "Up," "Right," "Left," and "Down."In this scenario, the disk's angular velocity is increasing in the counterclockwise direction. According to the right-hand rule, the direction of angular velocity and angular acceleration will point "up" along the axis of rotation when the disk is speeding up in that direction.**Correct Answer:** Up

Up Left Right Down A spinning disk is rotating at a rate of 4 rad/s in the counterclockwise direction as shown in the figure. If the disk is speeding up at a rate of 4 rad/s2, what is the direction of the angular acceleration vector? right down left up

Up Left Right Down A spinning disk is rotating at a rate of 4 rad/s in the counterclockwise direction as shown in the figure. If the disk is speeding up at a rate of 4 rad/s2, what is the direction of the angular acceleration vector? right down left up
