**Physics Problem: Maximum Compression of a Spring**

**Problem Statement:**
An object moving along a horizontal track collides with and compresses a light spring (which obeys Hooke's Law) located at the end of the track. The spring constant is **38.7 N/m**, the mass of the object is **0.240 kg**, and the speed of the object is **1.70 m/s** immediately before the collision.

**Question (a):** 
Determine the spring's maximum compression (in meters) if the track is frictionless.

[Answer Box: ________ m]

**Analysis:**
To solve this problem, you would use the conservation of energy principle. The initial kinetic energy of the object is converted into the potential energy stored in the spring upon maximum compression. Use the formula:

\[ \frac{1}{2}mv^2 = \frac{1}{2}kx^2 \]

where:
- \( m \) is the mass of the object,
- \( v \) is the initial velocity of the object,
- \( k \) is the spring constant,
- \( x \) is the maximum compression of the spring.

By rearranging and solving for \( x \), you determine the spring's maximum compression.
