No, two objects having the same velocity does not necessarily mean that they have the same mass. Velocity is a measure of how fast an object is moving in a particular direction, while mass is a measure of the amount of matter in an object.
The mass of an object determines its inertia, which is the resistance of an object to changes in its motion. Objects with greater mass have greater inertia, meaning they require more force to accelerate or decelerate compared to objects with smaller mass.
Velocity depends on the applied force and the mass of the object according to Newton's second law of motion: F=maF = maF=ma, where FFF is the force applied to the object, mmm is the mass of the object, and aaa is the acceleration produced. If two objects experience the same force and have the same acceleration, their masses may be different.
In summary, while two objects with the same velocity could have the same mass, it is not a guarantee. The mass of an object is an independent property and can vary regardless of the velocity.
