Question

How fast will an object with a mass of `15 kg` accelerate if a force of `48 N` is constantly applied to it?

Answer 1

I calculate `3.2 ms^-2`

Explanation:

In this situation we have a `15 kg` object with a constant force of `48 N` being applied to it. We can use Newton's Second Law, `F=ma`, to solve this problem.

We're trying to find the acceleration `a`, so first we must rearrange the equation to make `a` the subject. This is done by dividing both sides by `m` to give us:

`a=F/m`

Now we just substitute in the numbers and do the division!

`a=48/15`
`a=3.2ms^-2`

Because the force applied is constant, this acceleration is also constant in size.
