Two diamonds begin a free fall from rest from the same height, 1.9 s apart. How long after the first diamond begins to fall will the two diamonds be 24 m apart?

There is not enough information to answer the question.
In a vacuum, the rate of acceleration due to gravity G is 9.8 meters per second at sea level. So after the first second, the first object would be 9.8 meters from the second object which is still at rest. After 1.9 seconds, the first object would be 27.4 meters from the second object. It doesn’t matter what the objects are – they could be feathers or bricks – in a vacuum.
Diamonds have a specific gravity of 3.5, which is important because of the effects of friction from the atmosphere. You would have to provide the pressure altitude, temperature, and humidity of the atmosphere, as well as coefficient of drag of the diamonds, because drag of the atmosphere would affect the rate of fall of the diamonds. You would also need to know the.
