What law out of newtons law is this statement ? please help ( The phone will hit the ground and the ground will push up with the same force. With a case, it is increasing the amount of time the phone hits the ground. This means the reaction force will be less.)

Newton's Third Law

Explanation:

Newton's Third Law is: If object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A.  

In this case, Object A is the Phone, and Object B is the ground. When the phone(Object A) hits the ground(Object B), the ground pushes up on the phone making the time increase and makes the reaction force less. Hope this helps!

thats not even an aswer choice

b. to discover aspects of the natural world.

hopefully i .
