Horizontal component of velocity

Reference no: EM13535560

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. he is standing at the edge of a rose garden 4.5 m below her window and 5 m from the base of the wall. How fast are the pebbles going when they hit her window?
