A toy rocket having mass 0.2 has a small fuel of mass `0.04` kg which it burna out in 6 s. Starting from rest on a horizontal smooth track , it gets a speed of 40 m/s after the fuel is burnt out completey . What will be the approximate thrust of the rocket ? What is the energy content per unit mass of the fuel ? (Ignore the small mass variation of the rocket during fuel burning )

To solve the problem step by step, we will break it down into two parts: finding the thrust of the rocket and calculating the energy content per unit mass of the fuel. ### Part A: Finding the Thrust of the Rocket 1. **Identify the given data:** - Mass of the rocket (m_rocket) = 0.2 kg - Mass of the fuel (m_fuel) = 0.04 kg - Final speed (v) = 40 m/s ...
