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?

The bug experiences 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 b/c of change of velocity/acceleration

To determine which force is greater at the point of impact and the acceleration of the bug compared to the semi, we need to analyze the situation.

First, let's understand the concept of force. Force is defined as the rate of change of momentum, which is mass times velocity (F = ma). When two objects collide, the force experienced by each object is determined by the change in their momentum.

In the given scenario, the bug is moving east at 1 m/s before the collision, while the semi-truck is moving west at 45 m/s. When they collide, the bug's velocity changes from east to west, and its momentum decreases. On the other hand, the semi-truck's velocity changes from west to west, meaning its momentum stays the same. The change in momentum for the bug is greater than for the semi-truck since the bug's initial velocity was much less than the semi-truck's velocity.

Since the bug experiences a greater change in momentum, the force acting on the bug is greater than the force acting on the semi-truck at the point of impact. Therefore, the statement "The bug experiences more force" is true.

Moving on to the question about acceleration, we need to understand that acceleration is the rate of change of velocity. Acceleration depends on the force applied to an object and its mass.

In this case, after the collision, the bug now travels west along with the semi-truck. Since both objects are moving in the same direction, their acceleration should be the same. The change in velocity and acceleration experienced by the bug and the semi-truck will depend on other factors such as their masses and the duration of the collision.

Therefore, the statement "The bug experiences more acceleration due to the change of velocity/acceleration" is not necessarily true. The bug and the semi-truck could have the same acceleration if there are no other external forces acting on them after the collision.
