I'm not sure, but I'm pretty sure it depends.
Answer: 5 m/s
Explanation:
Momentum = mv (mass*velocity)
60kg*m/s = (12kg)*(v)
v = (60kg*m/s)/(12kg)
v = 5 m/s
If you increase speed you have to increase force to keep a balance Newton's second law.
All these terms are related to an aircraft system. A pitch is a rotational motion around the side-to-side axis. It is a phenomenon when a plane is tilted upwards to increase lift of the tail or tilted downwards to decrease it. It is controlled by an elevator from the pilot maneuvering system.
