Charlie takes his 6000 kg avalanche truck and runs it into Jill's 2003 Chevy Trailblazer. If Jill's truck is red, how does the force acting on Charlie's truck compare to the force acting on Jill's truck?
The forces are equal in magnitude and opposite in direction. (Newton Law 3)
The forces are equal and opposite.

To determine how the force acting on Charlie's truck compares to the force acting on Jill's truck in a collision, we can use Newton's third law of motion, which states that every action has an equal and opposite reaction.
Since Charlie's truck ran into Jill's truck, we can assume that both trucks experienced the same force during the collision. Therefore, the force acting on Charlie's truck is equal to the force acting on Jill's truck.
It is important to note that the color of Jill's truck, whether it is red or any other color, does not affect the forces involved in the collision. The color is simply a visual characteristic of the truck and not relevant to the physics of the situation.
