The car with its passengers is traveling along a horizontal road when it suddenly runs onto a new piece of road surface, raised 5.5 cm above the old surface. Assume that this suddenly raises the wheels and the bottom ends of the springs through 5.5 cm before the body of the car begins to move upward. In the ensuing rebound, are the passengers thrown clear of their seats? To answer this, consider the maximum acceleration of the resulting simple harmonic motion, assuming the passengers do remain in their seats.
a) What is the maximum downward acceleration of the vehicle after it bounces? Enter the maximum acceleration of the car and passengers, assuming they do remain seated, as your first answer (without a sign),
b) Will the passengers would be thrown clear of their seats. just tell yes or no.
