Transcribed Image Text:**Title: Physics Problem: Motion and Collision**
**Problem Statement:**
An iron block with mass \( m_3 \) slides down a frictionless hill of height \( H \). At the base of the hill, it collides with and sticks to a magnet with mass \( m_4 \).
---
### Part A
**Question:**
What is the speed \( v \) of the block and magnet immediately after the collision?
**Answer Options:**
- \( v = \left( \frac{m_3 + m_4}{m_3} \right) \sqrt{2gH} \)
- \( v = \frac{m_4}{m_3} \sqrt{2gH} \)
- \( v = \frac{m_3}{m_4} \sqrt{2gH} \)
- \( v = \left( \frac{m_3 - m_4}{m_3} \right) 2gH \)
- \( v = \left( \frac{m_3}{m_4} \right) 2gH \)

### Part B
**Question:**
Now assume that the two masses continue to move at the speed \( v \) from Part A until they encounter a rough surface. The coefficient of friction between the masses and the surface is \( \mu \). If the blocks come to rest after a distance \( s \), which of the following equations would you use to find \( s \)?
**Answer Options:**
- \( \left( \frac{m_3}{m_4} \right) v^2 = \mu m_3gs \)
- \( \left( \frac{m_3}{m_4} \right) gH = \mu m_4gs \)
- \( \left( \frac{m_3 + m_4}{m_4} \right) gH = \mu m_3gs \)
- \( \left( \frac{m_3 - m_4}{m_3} \right) gH = \mu (m_3 + m_4) gs \)
- \( \left( \frac{m_3}{m_4} \right) gH = \mu (m_3 + m_4) gs \)
