The windshield of a speeding car hits a hovering insect. Consider the time interval from just before the car hits the insect to just after the impact. Which of the following are correct? (Select all that apply.)
Choose the system so that the change of momentum zero. Compare the change of momentum and the change in velocity of the car and the bug, respectively.
The magnitude of change of momentum of the car is bigger that that of the bug.
The system consists of the bug alone.
The system consists of the bug plus the car.
The magnitude of change of velocity of the car is bigger than that of the bug.
The magnitude of change of momentum of the bug is bigger than that of the car.
The magnitudes of the change of velocity are equal for car and bug.
The magnitudes of the change of momentum are equal for car and bug.
The system consists of the car alone.
The magnitude of change of velocity of the bug is bigger than that of the car.
