Physics Exam
This article is real, but I could swear I once saw this question on a test in a calc-based physics course. It's exactly the sort of thing that sadistic, mathematically-inclined science professors enjoy torturing their normally-craniumed students with...
1) A 1992 BMW 535i (statistics provided on cue sheet) is speeding along a motorway when it suddenly swerves, strikes a curb, launches across the lawn, and penetrates the wall of a residence 12 feet above ground level. The wall is parallel with and 55 feet from the curb. Impact point with the curb is centered on the wall. Assume a quarter tank of gas, a 150-lbs driver, one 150-lbs passenger, and properly inflated tires. Calculate the velocity and angle of incidence at the time of impact with the curb, as well as terminal velocity upon impact with the wall. Provide supporting calculations and graph for trajectory, as well as all vector analyses.
Bonus: Explain how the driver ended up underneath the front wheel.
Timed Question: 16 minutes

Without the height of the rock mound a few meters parallel to the house or the height of impact, it is impossible complete the calculations.
