Answer:43,200 Joules

Explanation:Kinetic energy can be found using the following formula:

where

mis the mass in kilograms andvis the velocity in m/s.We know the mass is 600 kilograms, and the car is moving at 12 meters per second. Therefore the mass is 600 kilograms and the velocity is 12 m/s.

m=600v=12Substitute these values into the formula.

First, evaluate the exponent: 12^2. 12^2 is the same as 12*12, which is equal to 144.

Multiply 600 and 144

Multiply 1/2 and 86,400, or divide 86,400 by 2.

Add appropriate units. Kinetic energy uses Joules, or J for units.

The kinetic energy of the car is

43,200 Joules.
