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 her and 5.0 m from the base of he wall. Find the magnitude of the velocity with which Romeo tosses the pebble up. Recall that when Romeo tosses the pebble upward the pebble has both an x-component as well as a y-component to its intitial velocity.

Find the angle at which Romeo launches the pebbles. You have bothcomponents of the intial velocity use these to find the launch angle. Give your answer in degrees and do not enter units.
