What is the kinetic energy of a 30 kg falling object when the object reaches a velocity of 20 m/s? A. 12,000 J B. 2,940 J C. 6,000 J D. 5,880 J

Question and answer

Answer : C. The kinetic energy of an object that has a mass of 30 kilograms and moves with a velocity of 20 m/s is 6,000 J. k.e.=1/2 mv^2 =1/2*30*(20)^2 =15*400 =6000 kg m^2/s^2 =6000J
