[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]
F = ma
F = (4.2 kg)(3 m/s²)
[tex]\boxed{F = \text{12.6 N}}[/tex]
Therefore, the net external force exerted on the papaya is 12.6 N.
