Question

A ball has a mass of 140 g. What is the force needed to accelerate the ball at 25 m/s2? (Formula: F=ma)

Answer 1

Answer:

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

Explanation:

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

$F = m\cdot a$ (1)

Where:

$m$ - Mass, measured in kilograms.

$a$ - Acceleration, measured in meters per square second.

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

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

$F = 3.5\,N$

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