Speed of a vehicle at moment of impact

Click For Summary
SUMMARY

The discussion centers on calculating the speed of a Toyota Avensis required to move a Saab 93 estate approximately 10 feet sideways upon impact. The Saab weighs 1,600 kg, including an additional passenger of 100 kg, while the Toyota weighs 1,380 kg with two passengers totaling 130 kg. The scenario assumes dry conditions with no braking involved. However, participants emphasize the complexity of the calculation due to numerous variables, including impact angles and environmental conditions, making it impossible to provide an accurate speed estimate without detailed accident reconstruction data.

PREREQUISITES
  • Understanding of basic physics principles, particularly momentum and force.
  • Familiarity with vehicle dynamics and weight distribution.
  • Knowledge of accident reconstruction techniques.
  • Awareness of the factors affecting vehicle impact analysis.
NEXT STEPS
  • Research vehicle collision dynamics and momentum conservation principles.
  • Learn about accident reconstruction methodologies and tools.
  • Explore the impact of weight distribution on vehicle behavior during collisions.
  • Investigate the use of accelerometer data in analyzing vehicle impacts.
USEFUL FOR

This discussion is beneficial for automotive engineers, accident reconstruction specialists, and individuals interested in vehicle safety analysis and physics of collisions.

if a saab 93 estate approx weight 1600kg is hit in the passager door head on by a toyota avensis weighing 1380kg what speed does it have to be doing to move the saab 10 feet to the side.
additional weighs involved are saab plus one person 100kg
toyota additional two persons approx 130kg
dry conditions no breaking involved.
hope there are some people out there who can answer this,have to confess that electricity and everything associated with it is my bag and trying to work this out has just left me with a head ache...
thanks in advance

There are too many unknowns to get an accurate answer. We would have to reconstruct the accident from looking at the actual location, checking angles of impact, any accelerometer data, street conditions, etc. There is zero chance for a short message board post to contain enough information for even a rough estimate.
