Answer:
Assuming that the masses of the cars are the same
9 times
Explanation:
Kinetic energy can be computed using the formula:

Where:
KE = Kinetic energy
m = mass
v = velocity
As you can see in your problem, the velocity of the the first car mentioned is 3 times faster.
Looking at the the formula, velocity is raised to two (2). So if we put it in terms of equations this is how it will look:
Let v = velocity of the slower car
Car 1: velocity = (3v)



The increase is by a factor of 9.
Answer:
Density is defined as the relationship between the mass and volume of a substance
Explanation:
Density is defined as the relationship between the mass and volume of a substance. A unit of measurement can be g / ml. The greater the mass of the substance, the greater the density value
The caterpillar population will develop resistance to the pesticide if any of them survived it because they were genetically different from the rest.
Answer:
Sand Dunes serve an important purpose by protecting inland areas from coastal water intrusion. They are able to absorb the impact and protect inland areas from high energy storms and act as a resilient barrier to the destructive forces of wind and waves.
