Problem 5: A car's bumper is designed to withstand a 4.0-km/h (1.1-m/s) collision with an immovable object without damaging the body of the car. The bumper cushions the shock by absorbing the force over a distance.

A car's bumper is designed to withstand a 4.0-km/h (1.1-m/s) collision with an immovable object without damage to the body of the car. The bumper cushions the shock by absorbing the force over a distance. Calculate the magnitude of the average force on a bumper that collapses 0.200 m while bringing a 900-kg car to rest from an initial speed of 1.1 m/s.

From 1946 through 1958, Col. John Stapp headed the U.S. Air Force Aero Medical Laboratory's studies of the human body's ability to tolerate high accelerations during plane crashes. Conventional wisdom at the time indicated that a plane's negative acceleration should not exceed 180 m/s2 (18 times gravitational acceleration, or 18g). Stapp and his colleagues built a 700-kg "Gee Whiz" rocket sled, track, and stopping pistons to measure human tolerance to high acceleration. Starting in June 1949, Stapp and other live subjects rode the sled. In one of Stapp's rides, the sled started at rest and 360 m later was traveling at speed 67 m/s when its braking system was applied, stopping the sled in 6.0 m. He had demonstrated that 18g was not a limit for human deceleration.   Find the time interval for Stapp and his sled to stop as their speed decreased from 67 m/s to zero.

A car’s bumper is designed to withstand a 4.0-km/h (1.1-m/s) collision with an immovable object without damaging the body of the car. The bumper cushions the shock by absorbing the force over a distance.    Calculate the magnitude of the average force on a bumper that collapses 0.175 m while bringing a 950-kg car to rest from an initial speed of 1.7 m/s, in newtons?
