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 force of the semi acting on the bug?
A)They are equal
B)The bug experiences more
C)The truck experiences more
D)Need more information
I got B b/c the truck weighs more
5)Consider the same bug and semi in Problem 4. What is true about the acceleration of the bug compared to the semi?
The bug experiences more
To answer question 4, we need to consider Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
When the bug collides with the windshield of the semi, the bug exerts a force on the windshield (action), and the windshield exerts an equal and opposite force on the bug (reaction).
Since the bug is splattered across the windshield and now travels in the same direction as the semi (west), we can conclude that the force exerted by the semi on the bug was greater than the force exerted by the bug on the semi. In this scenario, the correct answer is C) The truck experiences more force.
To answer question 5, we need to consider Newton's second law of motion, which states that the acceleration of an object depends on the net force acting on it and its mass.
The bug has a small mass compared to the semi-truck, and therefore, a smaller force was required to accelerate the bug. Since both the bug and the semi experience the same net force (as they collided), we can conclude that the bug experiences more acceleration than the semi. In this scenario, the correct answer is "The bug experiences more acceleration."
