Question

Which has a higher acceleration: a 10-kg object acted upon with a net force of 20 N or an 18-kg object acted on by a net force of 30 N?
A. Both accelerate at the same rate.

B. the 10-kg object

C. the 18-kg object

Answer 1

The first one accelerate at 2m/s
the second one accelerates at 1.6666m/s

therefore statement b. the 10kg object is your answer

hope this helps :)

Answer 2

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.

$F=m*a\\\\where:\\m=mass\\a=acceleration$

in order to obtain the acceleration we have to reordenate the formula:

$a=\frac{F}{m}$

The acceleration of the 10 kg object is:

$a=\frac{20N}{10kg}=2\frac{m}{s^2}$

The acceleration of the object of 18 kg is:

$a=\frac{30N}{18kg}=1.67\frac{m}{s^2}$

The biggest acceleration was for the object with less mass.
