### Problem Analysis: Rocket Motion with Thrust and Atmospheric Resistance

#### Problem Statement:
A rocket moves in a vertical plane and is being propelled by a thrust \( T \) of 32 kN. It is also subjected to an atmospheric resistance \( R \) of 9.6 kN. If the rocket has a velocity of 3 km/s and the gravitational acceleration is \( 6 \, \text{m/s}^2 \) at the altitude of the rocket, calculate:

- The magnitude of the acceleration of the rocket in \( \text{m/s}^2 \).
- The direction of the acceleration of the rocket relative to the ground in degrees.

#### Given Data:

- Thrust, \( T \) = 32 kN
- Atmospheric resistance, \( R \) = 9.6 kN
- Velocity of the rocket, \( v \) = 3 km/s
- Gravitational acceleration, \( g \) = 6 \( \text{m/s}^2 \)
- Time rate-of-change of the magnitude of velocity of rocket, \( a \) = 6 \( \text{m/s}^2 \)
- Radius of curvature of rocket's path, \( p \) = 3000 km
- Mass of rocket at the given instant, \( m \) = 2000 kg

#### Solution:

To solve the problem, use the following steps:

1. **Compute the net force acting on the rocket:**

    \( \text{Net force} = \text{Thrust} - \text{Atmospheric resistance} - \text{Gravitational force} \)

2. **Use Newton's Second Law to find the acceleration:**

    \( \text{Net force} = m \times a \)

3. **Determine the direction of acceleration:**

    Consider the forces acting in different directions and use trigonometric calculations to find the angle.

Since no specific detailed diagrams or graphs are provided in the image, you can create your diagrams to aid in understanding the forces and motion involved.

### Educational Insight:

#### Key Concepts:

- **Newton's Second Law of Motion:** It states that \( F = ma \), where \( F \) is the net force applied to an object, \( m \) is the mass of the object, and \( a \) is its acceleration.
  
- **Components of Force:** Here, the thrust is acting

**Problem 3/65**

In this educational diagram, we are presented with the schematic of a rocket subjected to forces. 

### Diagram Explanation:

- **Rocket Orientation**:
  - The rocket is shown tilted at an angle of 30° from the vertical axis.

- **Forces Acting on the Rocket**:
  - There are two main forces identified in the diagram:
    1. **Thrust Force (T)**: This force is shown emerging from the base of the rocket, directed along its axis of orientation. The arrow indicating thrust force is labeled with a "T".
    2. **Resultant Force (R)**: This force is depicted coming out from the tip of the rocket, also directed along the rocket’s axis. It is labeled with an "R".

### Angles and Orientation:

- The rocket’s angle of 30° from the vertical is explicitly marked with a dashed vertical line and an angular measurement indicating this inclination.
  
### Purpose and Use:

- This diagram can be utilized to study the vector components of forces acting on the rocket in its tilted position. It can help students understand how forces are resolved along different axes and the implications on the rocket’s motion.

This educational content is designed to aid in comprehension of mechanics and vector resolution in physics or engineering contexts.
