Answer:
The answer is 6 J
Explanation:
The kinetic energy of an object can be found by using the formula
[tex]KE = \frac{1}{2} m {v}^{2} \\ [/tex]
where
m is the mass
v is the velocity
From the question we have
[tex]KE = \frac{1}{2} \times 0.75 \times {4}^{2} \\ = \frac{1}{2} \times 0.75 \times 16 \\ = 0.75 \times 8[/tex]
We have the final answer as
6 J
Hope this helps you
