If two stones of 10 kg and 1 kg are dropped from a 1 km high tower, which will hit the ground with greater velocity? Which will hit the ground first? (Neglect air resistance)

When two stones, one of 10 kg and the other of 1 kg, are dropped from a height of 1 km, they will hit the ground with the same velocity, assuming no air resistance. This is because the acceleration due to gravity (9.8 m/s²) acts equally on both stones, regardless of their mass. The difference in mass does not affect the speed at which the objects fall. Both stones will hit the ground at the same time as well, since the time taken to fall is determined by the initial conditions and gravity, not the mass of the objects.
