B very loud, high-frequency sound B 5.0 M/s As the engine fires, it uses fuel, so it is much lighter at the end of the run than at the end of the run than at the start. In this analysis we assume that air resistance can be neglected. Equal to 35 PSI C the car exerts the same amount of force on the truck as the car exerts on the truck Eventually it will converge to the largest eigenvector, and the gain in norm for a single step is the associated eigenvalue.
