According to Newton's third law of motion, They will push away from each other in proportion to their masses. (I am in 7th grade and I learned this in the first chapter in science, it was mostly about Newton's first, second, and third law. You should see the definitions of them, it will help you a lot, trust me)
In physics, any change in velocity<span> is an acceleration. This means that an object moving at constant </span>speed<span>, but changing direction, is accelerating. </span>Speed<span>–time and </span>velocity<span>–time </span>graphs<span>both give information about the motion of an object that is accelerating.

Answer:
1600 years half life
3200/1600 is 2 half lifes
first half life takes the sample to 1/2 it's original amount and the second takes it to 1/4 of it's original amount
so 1/4*7gm is 1.75gm
