In a completely inelastic collision, a 3kg mass moving at 6m/s collides with a stationary 2kg mass. What is the final ve
For elastic collision, momentum and kinetic energy conserved: m1v1+m2v2=m1v1'+m2v2' and ½m1v1²+... per NCERT. Solving gives velocities matching 3 m/s. Inelastic loses energy. So option A is correct.
