When you are traveling in your car at highway speed, the momentum of a bug is suddenly changed as it splatters into your windshield. Compared with the change in momentum of the bug, by how much does the momentum of your car change
By the law of conservation of the momentum The car-bug system moment will remain the same before and after the collision. And since the mass of the car is much higher than the bug, the change in velocity of the car will be negligible as compared to the change in velocity of the bug and hence the change in momentum of the bug will be very large and change in momentum of the car will be negligible.
