Question

**Title: Collision and Momentum Experiment**

**Diagram Explanation:**

The diagram shows two blocks involved in a physics experiment.

- **Block A**:
- Mass (\( m_A \)) = 3 kg
- Initially pushed by a hand with a force of 75 N over a distance (\( \Delta x \)) of 2 m.
- Moves at a velocity (\( v_A \)) = 8 m/s over a rough surface with a coefficient of kinetic friction (\( \mu_k \)) = 0.4.

- **Block B**:
- Mass (\( m_B \)) = 6 kg
- Initially at rest.
- After the collision, moves to the right with a velocity of 5 m/s.

**Text Explanation:**

A hand pushes block A (mass = 3 kg) with a constant force \( N_{\text{hand}, A} = 75 \) N for a distance \( \Delta x = 2 \) m along a mostly frictionless table. Block A speeds up from rest and travels at a speed of 8 m/s after sliding over a rough section of the table (\( \mu_k = 0.4 \)). Block A then collides with block B (mass = 6 kg), initially at rest.

After the collision, block B moves to the right with a velocity of 5 m/s. The problem asks to find the velocity (magnitude and direction) of block A immediately after the collision.

**Options:**

A) +2 m/s
B) +3 m/s
C) -3 m/s
D) -2 m/s
E) +5 m/s

**Answer Choices:**

- O A
- O B
- O C
- O D
- O E

This exercise requires understanding of concepts like force, friction, and conservation of momentum in a collision.
