Answer:

That object has a kinetic energy of #6.25 J.#

Explanation:

Let's begin with using the formula below:

We already have the mass and velocity, and both have good units so all we have to do is plug the given values into the equation:

# KE =(.50)(8kg)(5/4m/s)^(2)#
#KE = 6.25kgxxm^(2)/s^(2)#

#KE = 6.25J#
