[tex]\tt{\huge{\blue{Explanation:}}}[/tex]
The force acting on an object is given by
[tex]\boxed{F_{net} = ma}[/tex]
where:
[tex]F_{net} =[/tex] net force
m = mass
a = acceleration
[tex]\tt{\huge{\red{Solution:}}}[/tex]
[tex]F_{net} = F_{applied} - F_{friction}[/tex]
[tex]F_{net} = \text{15 N} - \text{6 N}[/tex]
[tex]F_{net} = \text{9 N}[/tex]
[tex]F_{net} = ma[/tex]
[tex]\dfrac{F_{net}}{m} = \dfrac{ma}{m}[/tex]
[tex]a = \dfrac{F_{net}}{m}[/tex]
[tex]a = \dfrac{\text{9 N}}{\text{5 kg}}[/tex]
[tex]\boxed{a = \text{1.8 m/}\text{s}^{2}}[/tex]
Therefore, the acceleration of the object is 1.8 m/s².
