Question

Calculate the kinetic energy of a 8 kg object moving at a velocity of 4 m/s.

Answer 1

the answer to your question is 200 J

Answer 2

64 J

Step-by-step explanation:

The kinetic energy of an object can be found by using the formula

`k = (1)/(2) m {v}^(2) \\`

m is the mass

v is the velocity

From the question we have

`k = (1)/(2) * 8 * {4}^(2) \\ = 4 * 16`

We have the final answer as

64 J
