Question

Approximately how much kinetic energy does an object have from its motion if its mass is 150-kg and it is moving at a speed of 5.0 meters per second?

Answer 1

The object has a kinetic energy of `375 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)(150kg)(5.0m/s)^(2)`
`KE = 375kgxxm^(2)/s^(2)`

`KE = 375J`
