Blocks with masses of 1.0 kg, 7.0 kg, and 9.0 kg are lined up in a row on a frictionless table. All three are pushed forward by a 20 N force applied to the 1.0 kg block.

A) How much force does the 7.0 kg block exert on the 9.0 kg block?

B) How much force does the 7.0 kg block exert on the 1.0 kg block?

I am unsure of where to start or an equation to even use. help on how to solve it would be greatly appreciated
