Answer:

112 J

Explanation:

The kinetic energy of a body is given as:

[tex]KE = \frac{1}{2}mv^2[/tex]

where m = mass

v = velocity

The mass of the ball is 3.5 kg.

The velocity of the ball is 8 m/s.

The kinetic energy of the ball is therefore:

[tex]KE = \frac{1}{2} * 3.5 * 8^2\\ \\KE = 112 J[/tex]
