A rocket with a lift off mass 20000 kg is blasted upwards with a net initial acceleration of `5 ms^(-2)` Calculate the initial thrust (force) of the blast.

Explanation

To calculate the initial thrust (force) of the rocket blast, we can follow these steps:

### Step 1: Identify the given values
- Mass of the rocket (m) = 20,000 kg
- Net acceleration (a) = 5 m/s²
- Acceleration due to gravity (g) = 10 m/s² (approximately)

### Step 2: Write down the forces acting on the rocket
