Question
Here are the equations I only need help with part e please
![**Newton's Second Law and Tension Analysis**
**Equations:**
(b) Newton’s Second Law for \( m_1 \) in terms of the tension \( T \) and the weight \( m_1g \) can be written as:
\[ \sum F_y = T - m_1g = m_1a_1 \]
(c) Newton’s Second Law for \( m_2 \) in terms of the tension \( T \) and the weight \( m_2g \) can be written as:
\[ \sum F_y = T - m_2g = m_2a_2 \]
**Question:**
(d) How are \( a_1 \) and \( a_2 \) related? What are the directions of \( a_1 \) and \( a_2 \)?
- A. \( a_1 \) is greater than \( a_2 \)
- B. \( a_1 \) is less than \( a_2 \)
- C. \( a_1 \) and \( a_2 \) have the same magnitude and direction
- D. \( a_1 \) and \( a_2 \) have the same magnitude but opposite directions
**Correct Answer:** D. \( a_1 \) and \( a_2 \) have the same magnitude but opposite directions.
**Consider:**
How will the equations from part (b) and (c) change considering the relationship between \( a_1 \) and \( a_2 \)?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3c88c0f8-77ed-4c7d-88e7-edca22160ba0%2F65833c7d-99cc-4137-9689-28ee80b4eb15%2F2mqvo01_processed.jpeg&w=3840&q=75)

**Correct Answer:** D. \( a_1 \) and \( a_2 \) have the same magnitude but opposite directions.
**Consider:**
How will the equations from part (b) and (c) change considering the relationship between \( a_1 \) and \( a_2 \)?

Transcribed Image Text:**Solve with Numerical Values**
**Block 1** has a mass of 2.5 kg and **Block 2** has a mass of 4 kg.
(e) Using the rewritten equations from part (b) and part (c) and part (d), find the magnitude of the acceleration of the two blocks.
- \( a = \frac{2}{\sqrt{6}} \) m/s\(^2\)
(f) Calculate the tension in the string.
- \( T = \frac{6}{\sqrt{5}} \) N
**Think:** How would the answers for part (e) and (f) change if instead you chose downward as positive and upward as negative direction?
