Documentation:FIB book/problems/Accident Reconstruction

From UBC Wiki

Assume a rear-end collision takes place on a T-crossing road. The insurance company tried to find out whether the driver was speeding at the intersection. From Figure 2, Vehicle 1(Blue Tesla Model 3) was rear end on the vehicle 2 (red). Vehicle 2 was stationary parked on the side of the road. The damage dimension is given by an accident reconstruction form (Figure 1). Assume A=800n/cm , B=80n/cm^2, Speed limit is 15m/h.

Question 1

Using the Barrier Equivalent Velocity method to find out the speed before the collision happened.

Question 2

Give analysis on whether the driver was speeding or not at that time (consider the definition of BEV). 

Question 3

Give a short summery about what types of the collision of the example and what injuries the driver might get.
