Angular speed, acceleration and displacement

Angular acceleration is defined as the rate of change in angular velocity with respect to time. It has both magnitude and direction. So, it is a vector quantity.

Angular Position

Before diving into angular position, one should understand the basics of position and its importance along with usage in day-to-day life. When one talks of position, it’s always relative with respect to some other object. For example, position of earth with respect to sun, position of school with respect to house, etc. Angular position is the rotational analogue of linear position.

Question

100%

The figure shows a uniform disk that can rotate around its center like a merry-go-round. The disk has a radius of 2.4 cm and a mass of 17 grams and is initially at rest. Starting at time \( t = 0 \), two forces are to be applied tangentially to the rim as indicated, so that at time \( t = 1.3 \) s the disk has an angular velocity of 300 rad/s counterclockwise. Force \( F_1 \) has a magnitude of 0.0995 N. What is the magnitude \( F_2 \)?

**Diagram Explanation:**

- The diagram depicts a circular disk with arrows representing tangential forces.
- Force \( F_1 \) is applied in a clockwise direction.
- Force \( F_2 \) is applied in a counterclockwise direction opposite \( F_1 \).
- The disk rotates counterclockwise under the influence of these forces.
