Answer:
Stunt Car A experiences a large force over a short period of time. Stunt Car B experiences a small force over a long period of time. Because of the force experienced by Stunt Car A, it will sustain more damage than Stunt Car B.
Explanation:
Both cars have the same mass and velocity, therefore they have the same momentum. During the collision, the total momentum of the car A and brick wall is conserved as well as the total momentum of the car B and the pile of leaves.
However, if we are to investigate the damage on each car, we should look at the cars not the whole system. So, the momentum difference between the cars gives us the impulse that the car felt.
Since the Car A will crash the wall quicker than the other car crashes through the pile of leaves,
which gives us

Explanation:
The potential energy stored in the spring will impart kinetic energy into the dart:
substitute the values:
The amplitude of the wave's electric field is times if the intensity of some electromagnetic wave doubles.
- What is electromagnetic wave:
Electromagnetic waves also called EM waves, are waves that are created as a result of vibrations between an electric field and magnetic field.
The formula of Intensity of electromagnetic wave:
- I = 1/2 ( c* ε(0)* E(0)^2 )
where c is speed of light
E is amplitude of electric field
here Intensity of EM waves doubles so,
I' = 2*I
we can say that,
I ∝ E^2
E = sqrt ( I )
E' = sqrt ( 2*I )
hence
E' = * E
so, the amplitude of the wave's electric field is times if the intensity of some electromagnetic wave doubles
