Blocks with masses of 1 kilogram, kilogram, and 3 kilogram are lined up in a row on a frictionless table. All three are pushed forward by a 12 Newton Force applied to the 1 kilogram block. Draw a free body diagram of all 3 blocks. How much force does the 2 kilogram block insert on the 3 kilogram block? How much force does a 2 kilogram block exert on the 1 kilogram block?
