Question

Romeo is throwing pebbles gently up to Juliet's window, and he wants the pebbles to hit the window with only a horizontal component of velocity. He is standing at the edge of a rose garden hhh = 9.6 mm below her window and LLL = 8.2 mm from the base of the wall 

How fast are the pebbles going when they hit her window?
