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 determine the forces acting on the bug and the semi-truck, we need to consider Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
4) Force: At the point of impact, the bug exerts a force on the windshield of the semi-truck, and the semi-truck exerts an equal but opposite force on the bug. Since the truck is moving west and the bug splatters across the windshield (also moving west), the force exerted by the bug on the semi is equal to the force exerted by the semi on the bug. Therefore, the correct answer is A) They are equal.
5) Acceleration: The acceleration experienced by an object is determined by the net force acting on it and its mass (F = ma). In this case, the bug and the semi-truck experience the same force at the point of impact (as determined in question 4), but their masses are different. Since the bug has a much smaller mass compared to the semi-truck, it will experience a larger acceleration. Therefore, the correct answer for this question is B) The bug experiences more acceleration.
