A jet airplane travelling at the speed of ` 500 km h^(-1)` , ejects the burnt agses at the speed of `1100 km h^(-1)`, relative to the jet airplance. Find the speed of the burnt gases .w.r.t. a stationary onserver on earth.

Explanation

To find the speed of the burnt gases with respect to a stationary observer on Earth, we can follow these steps:

### Step 1: Understand the Given Information
We know:
- Speed of the jet airplane (V_jet) = 500 km/h (upward)
- Speed of the burnt gases relative to the jet (V_gases/jet) = 1100 km/h (downward)

### Step 2: Define Directions
