What is the Kinetic Energy of a 2 kg object moving at a velocity of 12 m/s?

  • 288 Joules.
  • 24 Joules.
  • 144 Joules.

Explanation from PART66Online

Kinetic energy is one half m v squared = 0.5 x 2 x 12 squared = 0.5 x 2 x 144 = 144 J. Because velocity is squared, the 24 J distractor (which omits the square) is far too small.

Ek=0.5*m*v^2
Ek=0.5*2*12^2
Ek=0,5*2*144=144 J
