Question

The young college student atop the dorm, angrily throws her history notebook from the roof of the building in a horizontal motion. She throws it at an amazing 8.25 m/s. The dorm is 25 meters high. The astute physics student quickly runs over with a trash can to “catch” the notebook. Where should the trash can be placed relative to the base of the building? Also determine the time of flight and the velocity vector of the notebook at impact.
