A bug flies into the windshield of a car going the opposite way. Which of the following are true.
|
|
the force of impact is the same for both
|
|
|
the impulse is the same for both
|
|
|
the acceleration of the bug is larger than the truck
|
|
|
A, B, and C are all true
|
Explanation:
Detailed explanation-1: -Answer: force by bus is greater as inertia contained in body is more in bus than bug.
Detailed explanation-2: -(b) True-Impulse = (force)(time). The forces on the bug and the car are equal (see part (a)), and Newton’s Third Law also insists that the forces act at exactly the same times, so that the impulse exerted by the car on the bug and the impulse exerted by the bug on the car are the same size.
