Answer:
The answer is
<h2>40 J</h2>Explanation:
The kinetic energy of an object given it's mass and velocity can be found by using the formula
where
m is the mass
v is the velocity
From the question
m = 5 kg
v = 4 m/s
The kinetic energy is
We have the final answer as
<h3>40 J</h3>Hope this helps you
