Two stones are released from rest at a certain height, one $1 \mathrm{~s}$ after the other.

(a) Once the second stone is released, does the difference in their speeds increase, decrease, or stay the same?

(b) Does their separation increase, decrease, or stay the same?

(c) Is the time interval between the instants at which they hit the ground less than, equal to, or greater than $1 \mathrm{~s}$ ? (Use $x(t)$ curves to help you visualize this problem.)
