A stone is dropped from the roof of a building; 1.30s after that, a second stone is thrown straight down with an initial speed of 23.0m/s , and the two stones land at the same time. How long did it take the first stone to reach the ground? How high is the building? What are the speeds of the two stones just before they hit the ground?
