Can anyone help me with these questions please
**Problem 16.114** The reel of rope has an angular velocity \( \omega = 4.5 \, \text{rad/s} \) and angular acceleration \( \alpha = 8 \, \text{rad/s}^2 \). (Figure 1) **Figure** - The diagram shows a reel with a point labeled \( B \) on its perimeter and a central point labeled \( C \). The radius from \( C \) to the point \( B \) is indicated as \( 100 \, \text{mm} \). - The reel rotates about the central axis with angular velocity \( \omega \) and angular acceleration \( \alpha \). - Coordinate axes \( x \) and \( y \) are shown beneath the reel. **Part A** Determine the magnitude of the velocity of point \( B \) at the instant shown. Express your answer to three significant figures and include the appropriate units. **Answer Box:** Value | Units **Part B** Determine the direction of the velocity of point \( B \) at the instant shown. Express your answer using three significant figures. **Note:** Measured clockwise from the positive \( z \)-axis.
