SUMMARY
The average force required to bring a 1000 kg car traveling at 14 m/s to a stop in 0.08 seconds is calculated to be 175,000 N. This is derived using the formula F = mv/t, where m is the mass, v is the velocity, and t is the time. The average acceleration during the crash is determined to be 175 m/s², which is approximately 18 times the acceleration due to gravity. This calculation highlights the significant forces involved in automotive crash tests.
