Danica observes a collision between two vehicles. she sees a large truck driving down the road. it strikes a small car parked at the side of the road. complete the passage summarizing the collision.

on colliding, the truck applies a force on the stationary car, and the stationary car applies - a smaller, a greater, an equal- . and opposite force on the truck. the front of the truck is designed to crumple in order to - lower the force of impact, apply maximum force on the stationary car, accelerate both vehicles passengers - , which protects the well-being of the passengers.

Complete sentence:

On colliding, the truck applies a force on the stationary car, and the stationary car applies -An equal- . and opposite force on the truck. The front of the truck is designed to crumple in order to - Lower the force of impact, which protects the well-being of the passengers.

Explanation:

The first part - an equal - is a result of Newton's third law, which states that:

"When an object A exerts a force on an object B, then object B exerts an equal and opposite force on object A". In this particular case, the two objects are the truck and the car, so when the truck exerts a force on the car, the car exerts an equal and opposite force on the truck.

The front of the truck is designed to crumple, so that the time of the collision becomes longer: this way, the deceleration of the truck becomes smaller, as given by the equation

And therefore, the force on the truck becomes smaller, as given by Newton's second law:

if the acceleration is smaller, than the force is smaller.

On colliding, the truck applies a force on the stationary car, and the stationary car applies - An equal- . and opposite force on the truck. The front of the truck is designed to crumple in order to - Lower the force of impact- , which protects the well-being of the passengers.

Explanation:

As per Newton's III law we know that every action has equal and opposite reaction force

So here we know that when truck hits the car then force applied by the truck is same as that the car applied on the truck but the direction is opposite

Now we know that the front side of the truck is designed to crumple so that the time of collision will be increased and the impact of force will change the shape of that part.

This results lower force of impact and hence the passengers are protected from the impact

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.

i believe the answer is electric potential.
