How fast will an object with a mass of 7 kg accelerate if a force of 9 N is constantly applied to it?

The acceleration is approximately $1 , 2857 \frac{m}{s} ^ 2$

Explanation:

In this situation, we can use Newton's second law of motion, which states that force applied to an object is equal to mass times acceleration:

$F = m \cdot a$

$N = k g \cdot \frac{m}{s} ^ 2$

The given elements are the mass of the object and the force that is applied:

$F = 9 N = 9 k g \cdot \frac{m}{s} ^ 2$

$M = 7 k g$

Now we can set our equation the way we need it:

$a = \frac{F}{m}$

$a = 9 k g \cdot \frac{m}{s} ^ \frac{2}{7} k g$

$a \approx 1 , 2857 \frac{m}{s} ^ 2$
