Question

1. which is an example of the law of inertia after a collision?

a tractor trailer carrying a large boulder will stop after it collides with another object; however, the large boulder it is hauling will continue to move forward until a force act
if you are in a car and hit the dashboard after being in a collision, the dashboard will hit you with the same reactive force.
a car traveling at 80 mph will have greater damages after a collision than a car traveling at 25 mph.
if both a compact car and suv collide with a brick wall, the suv would suffer greater damage based on its greater mass.

Explanation:

The law of inertia (Newton's First Law) states that an object in motion stays in motion with constant velocity unless acted upon by an unbalanced force. In this option, the stopped trailer no longer acts on the boulder, so the boulder continues moving until a force stops it, which directly demonstrates inertia post-collision. The other options describe Newton's Third Law (reactive force) or relate to kinetic energy/damage from mass/speed, not inertia.

Answer:

A. A tractor trailer carrying a large boulder will stop after it collides with another object; however, the large boulder it is hauling will continue to move forward until a force acts on it.
