A car has a mass of 1000 kg and a momentum of 12 000 kg m / s.
What is its kinetic energy?

It's 7.2 x 10^10

I got that because I've put that into the calculator

but just transform it into a standard form = 72000000000

explanation:

the atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons.
