Question
### Problem Statement

A 22-gram bullet traveling at 280 m/s penetrates a 1.8 kg block of wood and emerges going 120 m/s.

### Part A

**Question:**  
If the block is stationary on a frictionless surface when hit, how fast does it move after the bullet emerges?

**Instruction:**  
Express your answer to two significant figures and include the appropriate units.

### Solution Area

The velocity of the block (\(v_B\)) is to be calculated based on the given conditions. Use the principles of conservation of momentum to determine how fast the block moves after being hit by the bullet. 

**Input Fields:**

1. **Value:** [Enter the numerical answer here]
2. **Units:** [Specify the unit of measurement] 

This problem provides a practical application of momentum conservation in physics, involving real-life scenarios such as bullet penetration and motion analysis on frictionless surfaces.
