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

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
