Question

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.`

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`
