Final answer:
The rocket will fly in the air with an acceleration of 50 m/s².
Step-by-step explanation:
To calculate the acceleration of the rocket, we can use Newton's second law of motion, which states that the net force acting on an object is equal to the product of its mass and acceleration.
We are given the mass of the rocket (4.0 kg) and the thrust generated by the rocket (200 N). We can use these values to find the acceleration.
We will plug in the values into the formula: F = ma, where F is the net force, m is the mass, and a is the acceleration.
200 N = 4.0 kg * a
Solving for a, we get a = 50 m/s².
Therefore, the rocket will fly in the air with an acceleration of 50 m/s².
