Answer:
25 J
Explanation:
The kinetic energy of an object is given by:
[tex]K=\frac{1}{2}mv^2[/tex]
where
m is the mass of the object
v is its velocity
For the ball in the problem, we have:
mass: m = 0.5 kg
v = 10 m/s
Substituting into the formula, we find
[tex]K=\frac{1}{2}(0.5 kg)(10 m/s)^2=25 J[/tex]
