**bobpursley**, Thursday, February 18, 2010 at 7:57pmCollege physics is not about plugging numbers into the correct formula. It is about analyzing, and using a math model to predict an outcome.

Here energy comes to mind. Some force over some distance is absorbing kinetic energy from the car.

Intial KE-FinalKE=Force*distance

1/2 mvi^2-1/2mvf^2=Force*130

solve for force.
