Solve the all given parts of following problem:
Problem: On a hot summer day in the state of Washington while kayaking, I saw several swimmers jump from a railroad bridge into the Snohomish River below. The swimmers stepped off the bridge, and I estimated that they hit the water 1.00s later.
Part I: How high was the bridge?
Part II: How fast were the swimmers moving when they hit the water?
Part III: What would the swimmer's drop time be if the bridge were twice as high?
I need expert help to salve the all parts of above problem.
