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 10 m, then another drop of 4 m to the bottom of the canyon, which has a horizontal floor. You kick a 0.76 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.

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