4. A bug is moving east at 1 m/s. A semi truck is moving west at 45 m/s. They collide and the bug is splattered across the windshield of the semi and now travels west. At the point of impact, which of the following is true about the force of the bug acting on the semi and the forece of the semi acting on the big?

Question

4. A bug is moving east at 1 m/s. A semi truck is moving west at 45 m/s. They collide and the bug is splattered across the windshield of the semi and now travels west. At the point of impact, which of the following is true about the force of the bug acting on the semi and the forece of the semi acting on the big?

A. they are equal (my answer)
B the bug experiences more
Cc the truck experiences less
D Need more information

5. Consider the same bug and semi from problem 4. What is true about the acceleration of the bug compared to the semi?
A. they are equal
B the bug experiences more (My answer)
C the truck experiences more
D. need more information

Are they correct?

Answer 1

To answer these questions, we need to apply Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. Now let's analyze each question.

4. At the point of impact, which of the following is true about the force of the bug acting on the semi and the force of the semi acting on the bug?

Since the bug collides with the windshield of the semi, the bug exerts a force on the windshield equal in magnitude and opposite in direction to the force the windshield exerts on the bug. Therefore, the correct answer is A) they are equal.

5. What is true about the acceleration of the bug compared to the semi?

Acceleration is directly proportional to the net force acting on an object. In this scenario, we have two forces: the force applied by the bug on the windshield, and the force applied by the windshield on the bug. Since these forces are equal and opposite, the net force on the bug is zero. Therefore, the bug does not experience any acceleration.

On the other hand, the semi-truck is moving west at a constant velocity of 45 m/s and does not experience any change in acceleration due to the bug's impact. Therefore, the bug experiences more acceleration compared to the semi, making answer B) the bug experiences more, correct.

In summary:
4. The forces acting on the bug and the semi are equal.
5. The bug experiences more acceleration compared to the semi.

Correct.

To answer these questions, we need to apply Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. Now let's analyze each question.
