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.
