A force of 30 N is applied to an object with a mass of 15 kg. What is the resulting acceleration?

Just remember when dealing with Newton II (where F=m*a), that F is the net (or resultant) force on the object. 30/15=2m/s

This is what i found on google “according to the collision theory, the following criteria must be met in order for a chemical reaction to occur: molecules must collide with sufficient energy, known as the activation energy, so that chemical bonds can break. molecules must collide with the proper orientation.” i hope this information you.
