Answer:

The force needed to accelerate the ball at 25 meters per square second is 3.5 newtons.

Step-by-step explanation:

From 2nd Newton's Law, the net force experimented by the ball (
), measured in newtons, is defined by:

$F = m\cdot a$ (1)

Where:

- Mass, measured in kilograms.

- Acceleration, measured in meters per square second.

If we know that
$m = 0.140\,kg$ and
$a = 25\,(m)/(s^(2))$ , then the net force needed to accelerated the ball is:

$F = (0.140\,kg)\cdot \left(25\,(m)/(s^(2)) \right)$

$F = 3.5\,N$

The force needed to accelerate the ball at 25 meters per square second is 3.5 newtons.
