Romeo is chucking pebbles gently up to Juliet's window and he wants the pebbles to hit the window with only a horizontal component of velocity (the least possible speed).

He is standing at the edge of a rose garden at H = 4.62 m below her window and at D = 5.21 m from the base of the wall. How fast are the pebbles going when they hit her window?
(in m/s)
