Fuel is consumed at the rate of 50 kg `s^(-1)` in a rocket. Find the thrust on the rocket if the velocity of the exhaust gases is 2 km `s^(-1)`. Also calculate the velocity of the rocket at the instant, when its mass is reduced to l/10th of its initial mass if its initial velocity is zero, (neglect gravity)

Explanation

To solve the problem step by step, let's break it down into two parts: calculating the thrust on the rocket and then calculating the velocity of the rocket when its mass is reduced to 1/10th of its initial mass.

### Part 1: Calculate the Thrust on the Rocket

1. **Identify the given values:**
- Rate of fuel consumption (dm/dt) = 50 kg/s
- Velocity of exhaust gases (u) = 2 km/s = 2000 m/s (convert km/s to m/s)
