Question
![### Part A: Determining the Velocity of Block A
In this exercise, you are asked to determine the velocity of block \( A \) if end \( B \) of the rope is pulled down with a speed of 3.0 m/s (Refer to Figure 1 for the setup).
Express your answer to three significant figures and include the appropriate units.
**Input Field:**
\[ v_A = \_\_\_\_\_\_ \, \text{Value} \, \_\_\_\_\_\_ \, \text{Units} \]

- **Submit**: Submit your answer for evaluation.
- **Request Answer**: If you are stuck and would like to see the answer.
- **Return to Assignment**: To go back to the main assignment page.
- **Provide Feedback**: To give feedback on this exercise.
#### Explanation:
- **Figure 1**: (Not provided in the text but assumed to show the setup of block \( A \) and end \( B \), likely illustrating the pulley system or the rope arrangement.)
- **Text Buttons**:
- The first button likely allows for formatting equations and inserting various mathematical symbols.

Transcribed Image Text:**Pulleys and Mechanical Advantage**
**Figure Explanation:**
The figure above shows a diagram of a pulley system. In this diagram:
1. **Pulleys:**
- Three pulleys are attached to a fixed overhead support.
- The pulley system is used to lift a load (`A`).
2. **Load:**
- The load, marked as `A`, is connected to a string or rope running through the pulley system.
3. **Effort:**
- A force `B` is applied to one end of the rope to lift the load `A`.
**Detailed Explanation:**
- **Pulley Systems:**
- Pulley systems are used to lift heavy loads with less effort.
- By combining multiple pulleys, the mechanical advantage increases, allowing a person to lift heavier objects more easily.
- **Mechanical Advantage:**
- The mechanical advantage of the system is determined by the number of pulleys used.
- More pulleys can distribute the load and reduce the force needed to lift the object.
**Practical Application:**
- This kind of pulley setup can be seen in various applications such as construction lifts, cranes, elevators, and theater stage rigging systems.
Understanding the functioning of pulley systems can help in designing efficient mechanical solutions in engineering and various practical applications.
