Question: A stone is dropped into a river from a bridge 49.9 m above the water. Another stone is thrown vertically down 1.14 s after the first is dropped. Both stones strike the water at the same time.

Part A: What is the initial speed of the second stone?

I don't understand how to get the answer. Can you please help me with this question?
