Acceleration of Two Objects That Push Off of Each Other


A toy consists of two figurines with masses of $80 \space g$ and $120 \space g$, respectively. When the figurines are pressed against each other, a spring between them gets compressed. Once the figurines are released, they push off of each other and are projected in opposite directions so that more massive figurine accelerates at $2.2 \space m/s^2$.
