1 If a heavy semi truck with a mass of 20,000 kg collides with smaller two door car that has a mass of 5000 kg. Which of the following statements is true?
a. The truck experiences more force than the car
b. The car experiences more force than the truck***
c. Both the truck and car experience the same amount of force
d. The difference in forces experienced by the car and the truck depend on which is moving faster
2 Under what situation can an object experience multiple forces, but yet experience no acceleration
a. An object can experience multiple forces, so long as the net force is zero
b. An object can experience multiple forces, so long as they all act in the same direction
c. An object can experience multiple forces, so long as the mass is proportional***
d. An object can experience multiple forces, so long as they are all the same type of force
*** = my answer
bruh wth are these answers
2. net force zero yields no accelerration
Answer:
Both the truck and car experience the same amount of force.
To answer question 1, we need to consider Newton's second law of motion, which states that force is equal to mass multiplied by acceleration (F = ma). In a collision between two objects, the force experienced by each object depends on the mass of the object and the acceleration it undergoes.
Given that the truck has a mass of 20,000 kg and the car has a mass of 5000 kg, we can conclude that the truck has a greater mass than the car. If both vehicles experience the same acceleration during the collision, according to the equation F = ma, it means the truck will experience more force than the car due to its greater mass.
Therefore, the correct answer to question 1 is a. The truck experiences more force than the car.
Now let's move on to question 2. If an object experiences multiple forces, the net force acting on the object is the vector sum of all the individual forces. According to Newton's second law (F = ma), when the net force acting on an object is zero, the object's acceleration is also zero. This means the object is either at rest or moving with constant velocity.
From the given options, the only statement that aligns with this explanation is a. An object can experience multiple forces, so long as the net force is zero. This allows the object to have no acceleration.
Therefore, the correct answer to question 2 is a. An object can experience multiple forces, so long as the net force is zero.
