Answer:
[tex]\boxed {\boxed {\sf a\approx 16.79 \ m/s^2}}[/tex]
Explanation:
Acceleration can be found by dividing the net force by the mass.
[tex]a=\frac{F}{m}[/tex]
The net force is 68 Newtons. Let's change the units to make later steps simpler.
1 Newton is equal to 1 kg*m/s², so the net force of 68.0 Newtons is also equal to 68.0 kg*m/s².
The mass is 4.05 kilograms.
[tex]F=68.0 \ kg*m/s^2 \\m=4.05 \ kg[/tex]
Substitute the values into the formula.
[tex]a=\frac{68.0 \ kg* m/s^2}{4.05 \ kg}[/tex]
Divide. Note that the kilograms (kg) will cancel each other out when dividing.
[tex]a=\frac{68.0 \ m/s^2}{4.05 }[/tex]
[tex]a=16.7901235 \ m/s^2[/tex]
Let's round to the nearest hundredth. The 0 in the thousandth place tells to leave the 9 in the hundredth place.
[tex]a\approx 16.79 \ m/s^2[/tex]
The acceleration is about 16.79 meters per square second.
