The image shows a physics problem where the equation of motion for a body with a mass of 2 kg is given as:

\[
x = 7 \cdot t + 4 \cdot t^2
\]

You are required to find:

1. **Gravitational Force (N)**: This is the weight of the object.
2. **Initial Momentum (kg·m/s)**: The momentum at \( t = 0 \).
3. **Initial Kinetic Energy (J)**: The kinetic energy at \( t = 0 \).
4. **Resultant Force (N)**: The net force acting on the body.

### Let's break down each step:

1. **Gravitational Force (N):**
   \[
   F_g = m \cdot g
   \]
   Where \( m = 2 \, \text{kg} \) and \( g \approx 9.8 \, \text{m/s}^2 \).
   \[
   F_g = 2 \times 9.8 = 19.6 \, \text{N}
   \]

2. **Initial Momentum (kg·m/s):**
   Momentum \( p \) is given by \( p = m \cdot v \), where \( v
