Problem: An object is dropped from a bridge. A second object is thrown downwards 1.0 seconds later. They both reach the water 20 m below at the same instant.

Part A: What was the initial speed of the second object?

Please explain your answer. I know substitution is involved so be sure to give a detailed explanation on that as well.
