Final answer:
In World War II, there were cases of airmen surviving falls from flaming airplanes without parachutes. We can calculate the deceleration using the given information.
Step-by-step explanation:
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. If we assume that a pilot's speed upon impact was 123 mph (54 m/s), then we can calculate the deceleration using the formula:
Acceleration = (Final Velocity - Initial Velocity) / Time
In this case, the time can be calculated using the equation:
Distance = Initial Velocity * Time + (1/2) * Acceleration * Time^2
Given that the distance is 3.0 m and the initial velocity is 54 m/s, we can substitute these values into the equation and solve for the deceleration.
