Question

If the collision results in an injury, death, or property damage of $___or more to one person's property and a report is not made by a law enforcement officer, you must report it to the Washington Department of Transportation on a Collision Report form within ___ days.

Answer 1

The question pertains to the conservation of momentum in a collision and involves calculating the post-collision velocity of the combined wreckage of two vehicles.

Step-by-step explanation:

If a collision results in an injury, death, or property damage of a certain amount or more, and a report is not made by a law enforcement officer, certain actions must be taken. However, what is of interest here is the Physics problem about a car collision and the resulting velocity of the wreckage. To solve for the velocity, we must apply the principle of conservation of momentum. We must find the combined momentum of both vehicles before the collision and set this equal to the momentum of the combined wreckage after the collision.

The equation for momentum is mass times velocity. The car has a mass of 1200 kg and a velocity of 60 km/hr east, while the truck has a mass of 3000 kg and a velocity of 40 km/hr north. To calculate the combined velocity after the collision, we have to use vector addition, since the cars are moving at right angles to one another.

Calculations and solving for the resultant velocity should follow from applying the principles of momentum conservation and considering the direction of velocities using trigonometry. However, it's important to resolve details such as converting velocities into consistent units to proceed with the calculations accurately.
