Answer:
the answer is B, 10-kg object
Explanation:
Because of Newton we know that if a force is applied to an object, it will have an acceleration on the same direction of the force applied.
[tex]F=m*a\\\\where:\\m=mass\\a=acceleration[/tex]
in order to obtain the acceleration we have to reordenate the formula:
[tex]a=\frac{F}{m}[/tex]
The acceleration of the 10 kg object is:
[tex]a=\frac{20N}{10kg}=2\frac{m}{s^2}[/tex]
The acceleration of the object of 18 kg is:
[tex]a=\frac{30N}{18kg}=1.67\frac{m}{s^2}[/tex]
The biggest acceleration was for the object with less mass.
