A3.0 n force and a 5.0 n force are acting in opposite directions on the same 5.0 kg ball. what is the magnitude of the acceleration of the ball?

To find the magnitude,

F = ma

Here the total force = 5 - 3 = 2N because the two forces are acting in opposite directions.

2 = 5a

2/5 = a

0.4 m/s^2 = a

I hope you like the answer.

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
