Question

18. 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. 6,000 J B. 5,880 J C. 2,940 J D. 12,000 J

Answer 1

Answer: 6,000 J

Step-by-step explanation:

Answer 2

Kinetic energy is defined
KE = 1/2 * m * v^2

Let's put in the numbers
KE = 1/2 * 30 * 20^2 = 6000

Therefore, the answer is a) 6000 J
