### Problem Statement:

A helicopter starts from rest at point A and travels along the straight-line path with a constant acceleration \( a \). If the speed \( v \) = 23 m/s when the altitude of the helicopter is \( h \) = 37 m, determine the values of \(\dot{r}\), \(\ddot{r}\), \(\dot{\theta}\), and \(\ddot{\theta}\) as measured by the tracking device at O. At this instant, \(\theta\) = 35°, and the distance \( d \) = 177 m. Neglect the small height of the tracking device above the ground.

### Diagram Description:

The diagram illustrates a helicopter following a linear path from point A up to a point above the ground, with the tracking device at point O. 

- **Points Noted:**
  - \( O \): Point where the tracking device is located.
  - \( A \): Starting point of the helicopter.
  - \( h \): Altitude of the helicopter from the ground, shown as a vertical line.
  - \( d \): Horizontal distance from point A to directly below the helicopter's current position.
  - \( r \): Distance from point O to the helicopter’s current location.
  - Line segment \( v \): Indicates the velocity vector of the helicopter.
  - \(\theta\): Angle between \( r \) and the horizontal ground.
  
### Diagram Components:

- **Tracking device \( O \)** at the origin, measuring positions, angles, and distances.
- **Helicopter Path**, denoted by a dashed orange line, beginning at point \( A \) and moving upwards.
- **Angle \( \theta \)**, the angle formed between \( r \) and the horizontal axis.

### Task:

Determine the following values:
- \(\dot{r}\) (Rate of change of \( r \))
- \(\ddot{r}\) (Acceleration along \( r \))
- \(\dot{\theta}\) (Rate of change of angle \( \theta \))
- \(\ddot{\theta}\) (Angular acceleration)

### Answers:

- \(\dot{r} =\) [_______] m/s
- \(\ddot{r} =\) [_______] m/s²
- \(\dot{\theta} =\) [_______] rad/s
- \(\ddot{\
