---

This question requires understanding Newton's second law of motion and applying it to calculate the velocity of an object under the influence of a constant force. The net force and mass of the rocket are given, as well as the time duration. You should calculate the acceleration using the formula \( F = ma \), then use this to find the velocity after the specified time using \( v = u + at \), where \( u \) is the initial velocity (0 m/s in this case).
