![### Problem Statement
A 2 kg block is moving at 5 m/s along a frictionless table and collides with a second 2 kg block that is initially at rest. After the collision, the two blocks stick together and then slide up a 45° frictionless inclined plane, as shown in the diagram below. Calculate the maximum distance \( L \) that the two blocks travel up the incline.
### Diagram Explanation
The diagram illustrates two stages of the blocks' movement:
1. **Pre-Collision Movement:**
- A 2 kg block is shown moving horizontally to the right at a speed of 5 m/s.
- A second 2 kg block is shown at rest on the same frictionless surface.
2. **Post-Collision Movement:**
- After the collision, the two blocks stick together and move as one unit.
- This combined block then slides up a frictionless inclined plane that makes a 45° angle with the horizontal surface.
- The length \( L \) represents the maximum distance the blocks travel up the incline.
### Key Concepts for Solution
- Conservation of Momentum: Since the surface is frictionless, momentum is conserved during the collision.
- Energy Conservation: The kinetic energy of the blocks is converted into gravitational potential energy as they move up the incline.
### Steps to Solution
1. **Calculate the velocity after collision using conservation of momentum:**
\[
m_1 v_1 + m_2 v_2 = (m_1 + m_2) v_f
\]
where \( m_1 = 2 \, \text{kg} \), \( v_1 = 5 \, \text{m/s} \), \( m_2 = 2 \, \text{kg} \), and \( v_2 = 0 \, \text{m/s} \).
2. **Convert the kinetic energy of the combined block after collision into gravitational potential energy to find the maximum height \( h \):**
\[
\frac{1}{2} (m_1 + m_2) v_f^2 = (m_1 + m_2) g h
\]
where \( g = 9.8 \, \text{m/s}^2 \).
3. **Relate the height \( h \) to the distance \( L \) up the incline using trigon](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F701927fd-ceaf-4fad-8338-7d1e3c22653c%2F16d1e196-ce31-4ad5-976f-b9c95ba85985%2Fgs3l6gc_processed.png&w=3840&q=75)
