Explanation:
We have:
We can calculate each component of the acceleration using its definition
The rate of change of momentum of the ball is
So for each coordinate:
And these are equal to the components of the net force since F=ma.
If magnitudes is what is asked:
<em>(N and </em><em> are the same unit).</em>
