1. The problem statement, all variables and given/known data Romeo is chucking pebbles gently up to Juliet's window, and he wants the pebbles to hit the window with a horizontal component of velocity. He is standing at the edge of a rose garden 8m below her window and 9m from the base of the wall. How fast are the pebbles going when they hit her window. 2. Relevant equations d=.5at^2 t=d/v t=√2d/a 3. The attempt at a solution I don't know how to find the speed when it has only a horizontal component of speed. Am I supposed to find how fast he should throw it so its apex is at her window?
