What is the kinetic energy of an object that has a mass of 30 kilograms and moves with a velocity of 20 m/s? A. 2,940 J B. 6,000 J C. 12,000 J D. 5,880 J

Question and answer

The kinetic energy of an object that has a mass of 12 kilograms and moves with velocity of 10 m/s is 600 J. K.E = 1/2 m*v^2 , 1/2 *12*10^2, 1/2 *12 *100 = 600 J
