You are standing at the top of a cliff that has a stairstep configuration. There is a vertical drop of 3 m at your feet, then a horizontal shelf of 6 m, then another drop of 7 m to the bottom of the canyon, which has a horizontal floor. You kick a 0.12 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? The acceleration of gravity is 9.8 m/s2 . Consider air friction to be negligi- ble.
part 2
How far from the bottom of the second cliff will the projectile land?
Answer in units of m.
this is physics
