Question

How fast will an object with a mass of `8 kg` accelerate if a force of `16 N` is constantly applied to it?

Answer 1

The object has an acceleration of `2m/s^(2)`

Explanation:

To find the acceleration, we have to use Newton's second law of motion equation:

We know the force and mass, both of which have the correct units. All we have to do now is rearrange the equation to solve for the acceleration like this:

`F/m=(cancel"m"xxa)/cancelm`

`F/m=a`

Plug in your known values:

`(16cancel"kg"xxm/s^(2))/(8cancel"kg")`

Therefore, the acceleration is `2m/s^(2)`

By the way, I changed `16N` to `16kgxxm/s^(2)` because it means the same thing. I wanted you to see how the units would cancel out:
