What is the kinetic energy of a #8 kg# object moving at #5/4 m/s#?

Answer 1

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

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#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
