[tex]\tt{\huge{\blue{Explanation:}}}[/tex]
The force acting on an object is given by
[tex]\boxed{F = ma}[/tex]
where:
F = force
m = mass
a = acceleration
[tex]\tt{\huge{\red{Solution:}}}[/tex]
Solving for m
F = ma
[tex]\dfrac{F}{a} = \dfrac{ma}{a}[/tex]
[tex]m = \dfrac{F}{a}[/tex]
[tex]m = \dfrac{\text{45 N}}{\text{3 m/}\text{s}^{2}}[/tex]
[tex]\boxed{m = \text{15 kg}}[/tex]
Therefore, the mass of the object is 15 kg.
