You are standing at the top of a cliff that has a stairstep configuration. There is a vertical drop of 6m at your feet then a horizontal shelf of 9m then another drop of 4m to the bottom of the canyon which has a horizontal floor. You kick a 0.3kg rock, giving it an initial horizontal velocity that barely clears the shelf below. What initial velocity will be required to barely clear the edge of the shelf  below you? The acceleration of gravity is 9.8m/s^2. Consider air friction to be negligible.

How far from the bottom of the second cliff will the projectile land?
