# What's the net force acting on an 18-kg object if the net force causes an acceleration of 3.0 m/s2?

Oct 1, 2015

The net force is $54 \text{N}$.

#### Explanation:

The net force acting on an object is determined by multiplying the mass in kg times its acceleration in $\text{m/s"^2}$, or $\text{F"_"net"=ma}$.

Known:
$m = 18 \text{kg}$
$a = 3.0 {\text{m/s}}^{2}$

Unknown:
$\text{F"_"net}$

Equation:
$\text{F"_"net"=ma}$

Solution:

$\text{F"_"net"=18"kg"xx3.0"m/s"^2=54 "N}$
