Here are the essential concepts you must grasp in order to answer the question correctly.
Newton's Second Law of Motion
Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This relationship is expressed by the formula F = ma, where F is the force, m is the mass, and a is the acceleration. Understanding this law is crucial for analyzing how different masses respond to the same force.

Kinetic Energy
Kinetic energy is the energy an object possesses due to its motion, calculated using the formula KE = 1/2 mv², where m is the mass and v is the velocity. In this problem, the kinetic energy of both balls can be compared to understand how the different speeds relate to their masses when acted upon by the same force.

Conservation of Energy
The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another. In this scenario, the work done by the constant force on both balls translates into kinetic energy, allowing us to set up equations that relate the forces, distances, and resulting speeds to find the unknown mass of the green ball.
