III Question 7 of 17 < View Policies Current Attempt in Progress The figure gives an overhead view of the path taken by a 0.163 kg cue ball as it bounces from a rail of a pool table. The ball's initial speed is 1.23 m/s, and the angle 8₁ is 55.4°. The bounce reverses the y component of the ball's velocity but does not alter the x component. What are (a) angle 82 and (b) the magnitude of the change in the ball's linear momentum? (The fact that the ball rolls is irrelevant to the problem.) (a) Number i Units (b) Number Units i

### Current Attempt in Progress The figure gives an overhead view of the path taken by a 0.163 kg cue ball as it bounces from a rail of a pool table. The ball's initial speed is 1.23 m/s, and the angle \(\theta_1\) is 55.4°. The bounce reverses the y component of the ball's velocity but does not alter the x component. What are (a) angle \(\theta_2\) and (b) the magnitude of the change in the ball's linear momentum? (The fact that the ball rolls is irrelevant to the problem.) ![Pool table diagram](IMAGE URL HERE) *Diagram Explanation:* The diagram shows a pool table with a cue ball moving in from the lower right towards a rail at an angle \(\theta_1\), and then bouncing off the rail. The angle \(\theta_1\) is the angle between the path of the incoming cue ball and the rail, measured counterclockwise from the x-axis. After bouncing, the ball's y component direction is reversed, and \(\theta_2\) is the angle between the path of the outgoing ball and the rail. #### Questions: (a) \(\theta_2\) - Number: [Input Field] - Units: [Input Field] (b) Magnitude of the change in the ball's linear momentum - Number: [Input Field] - Units: [Input Field] #### Additional Resources: - [eTextbook and Media] #### Answer Submission: - **Save for Later** - **Submit Answer** #### Attempts: 0 of 8 used

--- ### Problem Statement **Current Attempt in Progress** In Figure (a), a 4.8 kg dog stands on a 16 kg flatboat at a distance \( D = 9.2 \) meters from the shore. The dog walks 1.9 meters along the boat toward the shore and then stops. Assuming no friction between the boat and the water, find how far the dog is from the shore. (*Hint: See Figure (b). The dog moves leftward and the boat moves rightward, but does the center of mass of the boat + dog system move?*) #### Explanation of Figures: **Figure (a)**: This diagram shows the initial setup with a dog standing on a flatboat. The dog and the flatboat are floating in water, and the distance between the boat and the shore is 9.2 meters. **Figure (b)**: This diagram shows the displacement of both the dog and the boat after the dog starts moving. The arrows indicate the direction of movement: - The dog's displacement is shown moving leftward. - The boat's displacement is shown moving rightward. ### Required Input **Number**: (Enter the numerical value for how far the dog is from the shore) **Units**: (Select the appropriate unit for your answer) #### Interactive Elements - **eTextbook and Media**: Link - **GO Tutorial**: Link - **Save for Later**: Button - **Submit Answer**: Button #### Attempt Status - **Attempts Used**: 0 of 8 ---
