Determine the accelerations that result when a 12-N net force is applied to a 3-kg object and then to a 6-kg object.

• A 3-kg object experiences an acceleration of 2 m/s/s. A 6-kg object experiences an acceleration of 2m/s/s.  

• A 3-kg object experiences an acceleration of 4 m/s/s. A 6-kg object experiences an acceleration of 2 m/s/s.  

• A 3-kg object experiences an acceleration of 2 m/s/s. A 6-kg object experiences an acceleration of 4 m/s/s.  

• A 3-kg object experiences an acceleration of 4 m/s/s. A 6-kg object experiences an acceleration of 4 m/s/s.
