In a car crash, wearing a seat belt __________________.

Answer 1

In a car crash, wearing a seat belt

A. Keeps you from being thrown from the car

B. can reduce injuries

The answer is : C. all of the above

Further explanation

In Newton's law, it is stated that if the resultant force acts on an object of magnitude is zero, it can be formulated:

∑F = 0

This value is for stationary objects or objects that move in a straight line

So if the resultant force on an object is zero, the object that was initially stationary will continue to remain stationary, and the object that was initially moving will continue to move at a constant speed

The size of inertia is proportional to mass, the greater the mass of the object, the greater the inertia of the object.

In objects with mass that move translatively, the object will maintain its linear velocity

When we are in a vehicle that moves forward, then we will still maintain a state of forwarding motion. If our vehicle stops suddenly, then we keep moving forward so we will be pushed forward. From this point, the use of a safety belt serves to hold back our movements so that there are no fatal injuries or collisions.

Answer 2

Answer:

The correct option is (c) which is all of the above. In a car crash, wearing a seat belt keeps you from being thrown from the car and can reduce injuries.

Further Explanation:

The benefits of wearing a seat belt are listed below:

1. The seat belt ensures that you keep inside the car during the car crash or accident.
2. It keeps you away from steering wheel, dashboard, windshield and other parts of the car.
3. It deaccelerates your body.
4. It reduces or disperses the force on the body and absorbs the force which transfer that force to the areas where your body is comfortable.

The stats say that 48% of the car accidents for those who were not wearing their seat belt. Also, seat belt reduces the chance of fatal injuries by 60% and reduce by 65% from moderate to critical injuries.
