A force of 900 N is applied to a 9kg object. How fast will it accelerate?​

Sagot :

Answer:

Just remember when dealing with Newton II (where F=m*a), that F is the net (or resultant) force on the object.

Just remember when dealing with Newton II (where F=m*a), that F is the net (or resultant) force on the object.This means, in your case there would have to be no weight acting on the object, no friction and absolutely no other force, only then can you assume that F=120N.
