1. Lunch launch. Enriqueta goes to his physics class, jogging down the sidewalk at 3.05 m / s. Her husband Bruno realizes that she left in such a hurry that she forgot her lunch, so he runs to her apartment window, which is 43.9 m directly above the sidewalk, to throw it at her. Bruno throws the lunch horizontally 9.00 s after Henriette has passed under the window, and she catches him running. Ignore air resistance.
a) With what initial speed must Bruno have thrown the lunch for Enriqueta to catch him just before touching the sidewalk?
b) Where is she when she catches lunch?
