Assignment:
A car traveling at 20 m/s stops in a distance of 50 m. Assume that the deceleration is constant. The coefficients of friction between a passenger and the seat are p5 = 0.3 and ilk = 0.2.
Will a 70-kg passenger slide off the seat if not wearing a seat belt?
If they do slip, how does the passenger's acceleration compare to the car's?
Must Haves: Sketch with forces identified , Free-body diagram with axis labels, velocity vs. time graph for car, velocity vs. time graph for passenger.
1) What was th e acceleration of the car and what was the acceleration ofthe passenger?
2) What was the calculated displacement for the car, and what was thecalculated displacement for the passenger? What does this tell you about a passenger that is not wearing a seatbelt?
3) What coefficient of static friction could have prevented the passenger from sliding? Do you think this is reasonable?
