A skateboarder is trying to skate horizontally off a building and jump over a pool as shown! The pool is 25.0m wide and the roof of the building is 32.0m above where he will land. Neglect drag.
How long will the skateboarder remain in the air?
With what initial speed (in given units) does the skateboarder need to barely clear the pool?
Would the skateboarder clear the pool if he skated off the building with an initial speed of 27mph?
