A ball is dropped from a tall tower. Then, a few moments later a second ball is dropped from the same tower. At the moment the second ball is released, they are exactly $12\mathrm{.}0$ metres apart from each other. How far apart from each other are they after $3\mathrm{.}00$ additional seconds? What is the difference in their velocities at $1\mathrm{.}00$ second, $2\mathrm{.}00$ seconds, and $3\mathrm{.}00$ seconds?
