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

Answer 1

the 10-kg object has higher acceleration

Step-by-step explanation:

Answer 2

When a force F is acting on an object of mass m, the acceleration of the object is (Newton's second law)

`a= (F)/(m)`
The first object has a mass of 10 kg and a force of 20 N is acting on it, so its acceleration is

`a_1= (20 N)/(10 kg)=2 m/s^2`
The second object has a mass of 18 kg and a force of 30 N is acting on it, so its acceleration is

`a_2= (30 N)/(18 kg)=1.67 m/s^2`
So, the first object has higher acceleration.
