It will be 8000 joules. ( if the velocity of a car has been doubled, the KE will be quadrupled. Because the KE is directly proportional to the velocity squared.)
KE= 1/2 m v2

9 x 2000 = 18,000. 9 is the square of 3.
9 x 2000 = 18,000. 9 is the square of 3.
9 x 2000 = 18,000. 9 is the square of 3.

so if 2000=1/2*m*v12 when the velocity double the energy will increase 22 =4 times making 8000j

What units are kinetic energy measured in?
To measure kinetic energy:Let us suppose an object of mass m moving wtih velocity vKinetic Energy of that object= mv2/2
What is the kinetic energy of a 200kg boulder when it is 1000m above the ground?
Kinetic energy = 1/2 (mass) (speed)2 = 1/2 (0.2) (200)2 = 4,000 joules
How kinetic energy of an object changes when the speed of an abject doubles?
Assuming non-relativistic speeds: Doubling the speed will quadruple the kinetic energy.
What happens to an object's kinetic energy when its speed doubles?
-It increases
What is the kinetic energy of a 1 kg mass that is moving with a speed of 20 ms?
200 joules at 20m/s

If the of an object doubles Its kinetic energy doubles?
If the speed of an object doubles, its kinetic energy quadruples. This is because velocity is squared in the formula for kinetic energy.
What is the kinetic energy of an object that has a mass of 20 kg and a speed of 2.8m per second?
The object's kinetic energy is 78.4 joules.
If the speed of an object doubles the kinetic energy of the object?
At twice the speed, the kinetic energy will be four times greater.
What is the kinetic energy of a 200kg boulder when it is 1000m above the ground?
Kinetic energy = 1/2 (mass) (speed)2 = 1/2 (0.2) (200)2 = 4,000 joules
How do you compare kinetic energies on things that move?
Kinetic energy = (1/2)*mass*(speed)^2 where, in metric units, mass is in kilograms, speed is in meters/second, and kinetic energy is in Joules. So, you need to know the mass and the speed of the things.

Start with 20 joules if speed is doubled what is new kinetic energy?
80 (20 x 22).
What is a kinetic energy of an object that has mass of 20 kilograms and speed of 2.8ms?
78.4 joules at 2.8m/s
Is kinetic energy measured in mass?
The kinetic energy of any moving object is 1/2 of (its mass) x (the square of its speed). The SI unit of any kind of energy is Joules.
What is the similarities between kinetic energy and potential energy?
kinetic energy depends on speed an potential energy depends on height and mass
