The net force is #54"N"#.

Explanation:

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

Known:
#m=18"kg"#
#a=3.0"m/s"^2#

Unknown:
#"F"_"net"#

Equation:
#"F"_"net"=ma"#

Solution:

#"F"_"net"=18"kg"xx3.0"m/s"^2=54 "N"#
