Question

Consider this situation: A police officer arrives at the scene of an accident and finds a load of straw bales partly on the back of a pickup truck and partly on the hood of a Jaguar sedan. Both vehicles are facing in the same direction. The pickup is in front of the Jaguar. The truck driver claims that she was stopped at the stop sign when the Jag drove into the back of her truck. The Jaguar driver claims that he was stopped behind the pickup when the truck suddenly backed up. Given this information decide whether each statement is true or false.

True False  These results are impossible. The bales would have fallen forward in this type of accident.
True False  The pickup could have backed into the Jaguar.
True False  If the vehicles were both moving (truck in reverse and car forward), the pickup must have been moving faster.
True False  There is not enough information to determine who is at fault.
True False  The Jaguar must have driven into the pickup.
True False  Regardless of fault, the apparent motion of the bales results from them seeking the natural state of rest.

These are my incorrect attempts:

1	Incorrect. (Try 1)	Fri Apr 3 09:07:53 pm 2020 (PDT)	False True False True False True
2	Incorrect. (Try 2)	Fri Apr 3 09:21:00 pm 2020 (PDT)	False True True True False True
3	Incorrect. (Try 3)	Fri Apr 3 09:29:09 pm 2020 (PDT)	False False True False True True
4	Incorrect. (Try 4)	Sat Apr 4 08:49:33 pm 2020 (PDT)	False False False False True True

Answer 1

Application of law :

The above situation will be covered under the Newton's first law and will be solved based on the theory that ' An object at rest, continues to be in the same state while the object in motion continues to ne in that state unless external pressure is used to stop it. "

.

Statement 1:

False :

Explanation :

As per the Newton's first law, due to the inertia of truck in motion, in case it breaks, the bales loaded on truck will experience force in the opposite direction of resistive force causing bakes to fall on the car irrespective of the speed of truck. Thus the statement is False.

.

Statement 2:

True :

The statement is true because as the pickup backs the car, then applying the first law of motion the bales experience an apparent force in the opposite direction of the resistive force that the pickup experiences due to the collision with car.

.

Statement 3 :

True :

If the vehicles were both moving (truck in reverse and car forward), the pickup must have been moving faster because on account of the speed , the abrupt stop while hitting the Jaguar makes the straw fall out.

Statement 4:

False :

The above situation presents all necessary facts, information and evidences which makes the application of law possible to make a conclusion about who is at fault. So there is enough information to determine who is at fault.

Statement 5:

True :

The Jaguar must have driven into the pickup because In case it hit the pickup it would cause bales to spill out

.

Statement 6:

True :

It is true that regardless of fault, the apparent motion of the bales results from them seeking the natural state of rest because it was acted on by forces which actually made them fall out of the pickup.
