Judy, by chance, spots a potted plant falling outside the window at 3.84 m/s . Further down the same building, Judy boyfriend clocks the pot at 61 m/s .The acceleration of gravity is 9.8 m/s2 .How far apart are the friends?
Answer in units of m.

The time it takes to go between windows is (V2  V1)/g = 5.833 s
The average velocity during the interval is (V2 + V1)/2 = 32.42 m/s
The product of time and average speed is the distance between them. It must be a tall building!
