Question

How fast will an object with a mass of `16 kg` accelerate if a force of `20 N` is constantly applied to it?

Answer 1

`a=1.25m/s^2`

Explanation:

The second law of newton is `sumF=ma`

So if you want to have the acceleration:
`a=(sumF)/m`

You have
`sumF =20N`
`m=16 kg`

So:
`a=(20N)/(16kg)`
`a=1.25m/s^2`

Hope it helped!

Answer 2

`1.25 \ "m/s"^2`

Explanation:

We use Newton's second law of motion, which states that,

`F=ma`

• `m` is the mass of the object in kilograms

• `a` is the acceleration in meters per second

Solving for acceleration, we get,

`a=F/m`

Now, we simply plug in the given values, and get,

`a=(20 \ "N")/(16 \ "kg")`

`=1.25 \ "m/s"^2`
