6: In World War II, there were several reported cases of airmen who jumped from their flaming airplanes with no parachute to escape certain death. Some fell about 20,000 feet (6000 m), and some of them survived, with few life-threatening injuries. For these lucky pilots, the tree branches and snow drifts on the ground allowed their deceleration to be relatively small. Assume a pilot’s speed upon impact was 54 m/s and the trees and snow stopped him over a distance of 7.6 m. Use a coordinate system where down is positive and, assuming constant acceleration, find the pilot’s acceleration after impact, in meters per second squared.

You are an engineer in charge of designing a new generation of elevators for a prospective upgrade to the Empire State Building Before the state legislature votes on funding for the project, they would like you to prepare a report on the benefits of upgrading the elevators. One of the numbers that they have requested is the time it will take the elevator to go from the ground floor to the 102nd floor observatory. They are unlikely to approve the project unless the new elevators make the trip much faster than the old elevators. If state law mandates that elevators cannot accelerate more than 2.40 m/s² or travel faster than 11.3 m/s, what is the minimum time in which an elevator can travel the 373 m from the ground floor to the observatory floor? minimum travel time:
