The final requirement for a degree in geology is Field Camp, an 8 week field experience in which budding geologists must complete rigorous real-world mapping projects. To celebrate the end of field camp, one student threw his rock hammer off of a 78 m cliff with a horizontal velocity of 34 m/s. He was then reminded that he had one more day of field work, so he needed to go get his hammer. How far away from the cliff did he have to walk in order to find his hammer?
