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

Answer:

64 J

Explanation:

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

$k = \frac{1}{2} m {v}^{2}$

m is the mass

v is the velocity

From the question we have

$k = \frac{1}{2} \times 8 \times {4}^{2} \\ = 4 \times 16$

We have the final answer as

64 J

Hope this helps you
