What is the kinetic energy of a 0.50 kg ball traveling at 120 m/s

3600 J

Explanation:

Kinetic energy of an object is the energy posses by an object solely due to its motion.

It can also be defined as the amount of work that can be done when an moving object come to test.

Kinetic energy of an object can be calculated by the equation,

K. E. = ½mv²

Where m = mass, v = velocity

So you get,

K. E. = ½*0.5 * (120) ² = 3600 J
