We are given Bullet mass 0.1 kg, initial speed 500 ms Block mass 5 kg, initially at rest The bullet gets embedded into the block i.e., perfectly inelastic collision We are to find the final velocity Vf of the bullet-block system after collision Apply conservation of linear momentum Initial momentum Bullet p 0.1 500 50 kgms Block p 5 0 0 Total initial momentum 50 kgms
