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

Explanation

To solve the problem of calculating the initial thrust force of the rocket, we can follow these steps:

### Step 1: Understand the Forces Acting on the Rocket
When the rocket is launched, two main forces act on it:
1. The gravitational force (weight) acting downward.
2. The thrust force (force of the rocket engine) acting upward.

### Step 2: Calculate the Weight of the Rocket
