A 800 kg rocket is fired from earth so that exhaust speed is 1200 m/s. Then calculate mass of fuel burning per second, to provide initial thurst to overcome its weight. `(g=10m//s^(2))`.

Explanation

To solve the problem, we need to calculate the mass of fuel burning per second (dm/dt) to provide the initial thrust necessary for the rocket to overcome its weight.

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Mass of the rocket (M) = 800 kg
- Exhaust speed (V) = 1200 m/s
- Acceleration due to gravity (g) = 10 m/s²
