SUMMARY

The discussion centers on the forces and injuries experienced by occupants of two identical vehicles on a damp road, where one vehicle is stationary with brakes applied and the other is traveling at 15 mph. According to Newton's laws of motion, the forces acting on both vehicles will differ due to their states of motion, leading to varying injury outcomes for the occupants. The stationary vehicle experiences no acceleration, while the moving vehicle will undergo deceleration upon impact, resulting in distinct force distributions and potential injuries. A proper frame of reference, particularly one connected to the center of mass of the two vehicles, is essential for accurately describing the dynamics involved.

PREREQUISITES
  • Newton's laws of motion
  • Basic understanding of kinematics
  • Concept of frame of reference in physics
  • Knowledge of vehicle dynamics
NEXT STEPS
  • Study Newton's laws of motion in detail
  • Learn about kinematic equations and their applications
  • Research the concept of frame of reference in physics
  • Explore vehicle dynamics and crash analysis techniques
USEFUL FOR

Physics students, automotive engineers, safety analysts, and anyone interested in understanding the dynamics of vehicle collisions and their effects on occupants.

Homework Statement


Two identical vehicles 1 vehicle stationary and with brakes applied other vehicle traveling at 15mph. Road surface of good tarmacadam but damp after rain. Would occupants of both vehicle experience the same forces and would the injuries sustained be equal?

Homework Equations



Newtons laws of motion

The Attempt at a Solution



So long ago since I worked this at out college (50 years!) I can't remember formulae and method. Any help would be appreciated.

Choose a frame of reference connected with the center of mass of the 2 objects to discribe distance and velocity. Does this help?
