What's 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. 12,000 J C. 2,940 J D. 5,880 J
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. Solution: KE = 1/2 * m * v^2 KE = (1/2) * 30 * (20^2) KE = (1/2) *30* 400 KE = 6000 J

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.
Solution:
KE = 1/2 * m * v^2
KE = (1/2) * 30 * (20^2)
KE = (1/2) *30* 400
KE = 6000 J
