Question

There has been an accident involving two cars on a May day in great weather. Your job is to take photos of the vehicles as they are positioned, measurements, including the length of the skid marks (see sketch) You calculate the pavement's coefficient of friction and results and other findings are below.

Question: What is the force the cars experienced in the collision?

 

 

Accident Findings

  • The two cars stuck together and there are skid marks over 12.25 m
  • There are also skid marks over a distance of 30 m before the collision point (from car 1)
  • The posted speed limit on this street is 40 mph
  • Other data: m1 = 2500 kg, m2 = 1200 kg
  • Fn = 88.2 N & FA = 75.8 N (from friction blocks)
  • Collision lasted for 1.2 seconds.
