# How fast will an object with a mass of 16 kg accelerate if a force of 72 N is constantly applied to it?

Apr 4, 2018

${\text{4.5 m/s}}^{2}$

#### Explanation:

From Newton’s second law

$\text{F = ma}$

where

${\text{Acceleration" = "F"/"m" = "72 N"/"16 kg" = "4.5 m/s}}^{2}$

$4.5 \setminus {\text{m/s}}^{2}$

#### Explanation:

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

$F = m a$

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

• $a$ is the acceleration in meters per second

And so,

$72 \setminus \text{N"=16 \ "kg} \cdot a$

$a = \left(72 \setminus \text{N")/(16 \ "kg}\right)$

$= 4.5 \setminus {\text{m/s}}^{2}$
