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

the answer is B, 10-kg object

Step-by-step 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=(F)/(m)`

The acceleration of the 10 kg object is:

`a=(20N)/(10kg)=2(m)/(s^2)`

The acceleration of the object of 18 kg is:

`a=(30N)/(18kg)=1.67(m)/(s^2)`

The biggest acceleration was for the object with less mass.
