Answer:

The answer is 6 J

Step-by-step explanation:

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

$KE = (1)/(2) m {v}^(2) \\$

where

m is the mass

v is the velocity

From the question we have

$KE = (1)/(2) * 0.75 * {4}^(2) \\ = (1)/(2) * 0.75 * 16 \\ = 0.75 * 8$

We have the final answer as

Hope this helps you
