SUMMARY
The discussion centers on the physics of stopping an object moving at 10 m/s using the momentum of a photon, defined as ħk, where k is the wave vector. The conservation of momentum and energy equations are applied, leading to the conclusion that for the object to be stopped by elastic reflection of the photon, its mass must be zero. The calculations involve the relationship between the momentum of the photon before and after the collision and the kinetic energy of the object. The final derived equation indicates that the mass of the object is directly related to the wave vector of the photon and its velocity.
