Question

How fast will an object with a mass of `4 kg` accelerate if a force of `17 N` is constantly applied to it?

Answer 1

`4.25ms^-2`

Explanation:

Given,
Force = 17 N
Mass = 4 kg

we know that force is equal to the froduct of mass and acceleration of object .
`17 N = a *4` kg
a = 17N/4kg
`a = 4.25 ms^-2`

Answer 2

4.25 meters per second per second

Explanation:

To solve this, we use Newtons 2nd law of motion which states that `F` = `m*a`.
This means that a force `F` is required to make a body of mass `m` accelerate with an acceleration of `a`.

So if a body of `4 kg` is to be accelerated by a force `17 N` then its acceleration can be found by putting into the formula `F` = `m*a`.

Mass is `4 kg` so `m` = 4
Force is `17N` so `F` = 17
We get,

`17` = `4*a`
This gives us that `a`= `17/4` or `a` = `4.25`

Hence, the body accelerates with an acceleration of 4.25 meters per second per second
