Answer: The force that must be applied is 15 N.
Explanation:
Force exerted on the object is defined as the product of mass of the object and the acceleration of the object.
Mathematically,
[tex]F=m\times a[/tex]
where,
F = force exerted = ?
m = mass of the object = 3 kg
a = acceleration of the object = [tex]5m/s^2[/tex]
Putting values in above equation, we get:
[tex]F=3kg\times 5m/s^2=15N[/tex]
Hence, the force that must be applied is 15 N.
