Car 2 has twice the kinetic energy than Car 1.

Step-by-step explanation:

If a body of mass m moving at a speed of v, then its kinetic energy will be given by .

Now, given that the mass of car 2 is twice that mass car 1.

Let, the mass of car 2 is 2m and that of car 1 is m.

Therefore, if both cars moving with the same velocity v, then the kinetic energy of car 1 will be and the kinetic energy of the car 2 will be .

Hence, Car 2 has twice the kinetic energy than Car 1. (Answer)

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
