### Problem Statement

At the instant shown, the disk is rotating with an angular velocity of \( \omega = 2 \, \text{rad/s} \) and has an angular acceleration of \( a = 1 \, \text{rad/s}^2 \). Determine the velocity and acceleration of cylinder \( B \) at \( \Theta = 45^\circ \).

Neglect the size of the pulley at \( C \), use the Relative motion method.

### Diagram Explanation

The diagram shows a mechanical setup with a rotating disk, labeled \( A \), that has:

- A marked center point \( O \) around which the disk rotates.
- An angular velocity vector \( \omega \) indicating the rotational speed and direction.
- An angular acceleration \( a \) indicating the change in angular velocity.

A rod extending from point \( A \) to point \( C \) connects the disk to a pulley. The distance from the center \( O \) of the disk to point \( A \) is 3 ft, and from \( A \) to \( C \) is 5 ft. Cylinder \( B \) is connected to the pulley at \( C \) by a cable.

### Instructions

The task is to use the Relative motion method to find the velocity and acceleration of cylinder \( B \), given the initial conditions and the specific angle \( \Theta = 45^\circ \).
