You are standing at the top of a cliff that has a stairstep configuration. There is a vertical drop of 6 m at your feet, then a horizontal shelf of 5 m , then another drop of 4 m to the bottom of the canyon, which has a horizontal floor. You kick a 0.44 kg rock, giving it an initial horizontal velocity that barely clears the shelf below What initial horizontal velocity v will be required to barely clear the edge of the shelf below you?
