Argelia has a stack of schoolbooks sitting in the backseat of her car. When Argelia makes a sharp right turn, the books slide to
2 answers:
Answer:
The books are displaced to the left due to inertia and ultimately halt when impacted by the car door.
Explanation:
The movement of the books can be understood through Newton's first two laws:
- The first law (Law of Inertia): an object will remain at rest or continue moving in a straight line unless an unbalanced force acts upon it.
- The second law: if unbalanced forces act on an object, it experiences an acceleration that can be described by the formula
where F is the object's net force, m its mass, and a its acceleration.
Now let's relate this to the scenario:
- When Argelia makes a sharp right turn, the books, which are not secured in the car, maintain their straight-line motion due to inertia so they appear to move left as the car shifts right.
- Upon contacting the car door, the books cease moving due to the second law: the door exerts an unbalanced force, causing the books to decelerate and ultimately come to rest.

Answer:
d) v1 = v2 = v3
Explanation:
This can be determined through the principle of energy conservation. We assess the total mechanical energy E=K+U (the sum of kinetic energy and gravitational potential energy) at both the initial and final positions, ensuring they remain constant.

Answer: small barrel gun
Explanation:
It is noted that short barrel guns have a higher muzzle velocity for bullets compared to longer barrel guns.
Acceleration is determined by the change in velocity with respect to time.
For short barrel guns, the bullet reaches its muzzle velocity more quickly, leading to greater acceleration than that of bullets from long barrel guns.
