Final answer:
The mass of the rocket is determined using Newton's second law of motion, F = ma. Given the force of 1N and acceleration of 3m/s², the mass of the rocket is calculated to be 0.333 kg.
Step-by-step explanation:
The mass of the rocket can be determined using Newton's second law of motion, which states that the force exerted on an object is equal to the mass of the object multiplied by its acceleration (F = ma). Given that the acceleration (a) is 3m/s² and the force (F) is 1N, we can rearrange the formula to solve for mass (m) as follows: m = F/a. Plugging in the given values, m = 1N / 3m/s², we get that the mass of the rocket is approximately 0.333 kg.
