Being the solid physicist that you are, you proceed to photograph all the necessary information that you need to present the case. You pull a tape measure from the trunk of your car and record the following data:
• length of the skid marks = 24.2 m
• speed limit in this area is 70 kph
Now you can build your case…
You are to present an easy to follow report that shows the insurance company (who likely has limited Physics experience) that you were not speeding based on the laws of Physics.
Assuming that the brakes were "locked" and the car skidded for the entire 24.2 m before striking the moose, construct a free-body diagram that illustrates the forces which act on the car.
Free-body diagram of skidding car: Be sure to label all forces with appropriate symbols.
