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 6 m , then another drop of 4 m to the bottom of the canyon, which has a horizontal floor. you kick a 0.16 kg rock, giving it an initial horizontal velocity that barely clears the shelf below.1. What initial horizontal velocity v will be required to barely clear the edge of the shelf below you? The acceleration of gravity is 9.8 m/s2 . Consider air friction to be negligible. Answer in units of m/s.
2. How far from the bottom of the second cliff will the projectile land? Answer in units of m.
