Answer:
194,400 joules of kinetic energy.
Explanation:
Remember that to calculate the Kinetic energy you need to use the next formula:
[tex]Ke=\frac{1}{2}Mass*Velocity^2[/tex]
We know that Mass= 1200 kg and velocity is 18m/s, so we insert those values into the formula:
[tex]Ke=\frac{1}{2}Mass*Velocity^2\\Ke=\frac{1}{2}1200kg*(18m/s)^2\\Ke=194,400 joules[/tex]
So the kinetic energy of a car moving at 18m/s with a mass of 1200 kg would be 194,400 joules.
