# How fast will an object with a mass of 15 kg accelerate if a force of 30 N is constantly applied to it?

Jun 10, 2016

The acceleration will be $a = 2 \frac{m}{s} ^ 2$

#### Explanation:

According to Newton's Second Law the acceleration is equal to force divided by mass:

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

So in the given task the acceleration equals:

$a = \frac{30}{15} = 2$

$\left[a\right] = \left[\frac{N}{k g}\right] = \left[\frac{k g \cdot \frac{m}{s} ^ 2}{k g}\right] = \left[\frac{m}{s} ^ 2\right]$
