# How fast will an object with a mass of 16 kg accelerate if a force of 20 N is constantly applied to it?

Mar 30, 2018

$a = 1.25 \frac{m}{s} ^ 2$

#### Explanation:

The second law of newton is $\sum F = m a$

So if you want to have the acceleration:
$a = \frac{\sum F}{m}$

You have
$\sum F = 20 N$
$m = 16 k g$

So:
$a = \frac{20 N}{16 k g}$
$a = 1.25 \frac{m}{s} ^ 2$

Hope it helped!
P.S. Theres already similar questions that have been answered, but with different numbers: Like this one

$1.25 \setminus {\text{m/s}}^{2}$

#### Explanation:

We use Newton's second law of motion, which states that,

$F = m a$

• $m$ is the mass of the object in kilograms

• $a$ is the acceleration in meters per second

Solving for acceleration, we get,

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

Now, we simply plug in the given values, and get,

$a = \left(20 \setminus \text{N")/(16 \ "kg}\right)$

$= 1.25 \setminus {\text{m/s}}^{2}$
