A truck has a kinetic energy of 1200j and is traveling at 9 m/s what is the truck mass

Mass of truck = 29.62 kg (Approx.)

Explanation:

Given:

Kinetic energy = 1200 J

Speed of truck = 9 m/s

Find:

Mass

Computation:

The kinetic energy of a thing is the force that has attributable to its movement in physics.

Kinetic energy = [1/2][m][v]²

1,200 = [1/2][m][9]²

1,200 = [1/2][m][81]

Mass of truck = 29.62 kg (Approx.)

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.
