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 9.00 meters below her window and 11.0 m from the base of the wall.
(a) How long do the pebbles take to reach the window? sec
(b) How fast are the pebbles going when they hit her window? m/s
(c) What was the vertical component of the velocity of the pebble when it first leaves Romeo's hand? m/s
(d) What was the horizontal component of the initial velocity of the pebble (when the pebble first leaves Romeo's hand)? m/s
(e) What is the initial speed of the pebble? m/s
(f) At what angle above the horizontal did Romeo throw the pebble?
