John is standing on a boat dock at the water's edge on a hot summer day throwing stones into the lake. He throws the stones from a height of 3.0 meters above the water with a speed of 16 meters per second. If he aims the stones "down" toward the water am releases them at an angle of 15 degrees below the horizontal, how far out into the lake will they splash?

**Problem Statement:**

John is standing on a boat dock at the water’s edge on a hot summer day throwing stones into the lake. He throws the stones from a height of 3.0 meters above the water with a speed of 16 meters per second. If he aims the stones “down” toward the water and releases them at an angle of 15 degrees below the horizontal, how far out into the lake will they splash? 

**Explanation:**

This problem involves projectile motion, where a stone is thrown with an initial velocity at an angle below the horizontal. The key components to solve this problem are:

1. **Initial Height (h):** 3.0 meters
2. **Initial Speed (v):** 16 meters per second
3. **Angle of Release:** 15 degrees below the horizontal

**Objective:**

Determine the horizontal distance the stone travels before it splashes into the lake. 

To solve this, typically, we would break the velocity into horizontal and vertical components and apply kinematic equations considering the acceleration due to gravity.
