Standing side by side, you and a friend step off a bridge at different times and fall for 1.8s to the water below. Your friend goes first, and you follow after she had dropped 1.7m a. When your friend hits the water, is the separation between the two of you 1.7m, less than 1.7m, or more than 1.7m? Explain.  b. Show the separation from part a by calculating it.
