Question
**Problem Statement:**

A block of mass \( M_A \) on a frictionless plane inclined at an angle \( \theta \) is connected by a massless cord over a massless, frictionless pulley to a second block of mass \( M_B \) as shown.

**Diagram:**

The diagram displays two blocks. Block \( M_A \) is placed on an inclined plane that is at an angle \( \theta \), with a cord running over a pulley. The other end of the cord is attached to block \( M_B \), which is hanging vertically.

**Given:**

- \( M_A = 5M_B \)
- When released from rest, block \( B \) accelerates upward at an acceleration of \( 3 \, \text{m/s}^2 \).

**Question:**

What is the angle \( \theta \)?

Express your answer in radians, to at least one digit after the decimal point.
