Two balls have a race over a distance of $20\mathrm{.}0$ meters. The red ball travels at a constant velocity while the blue ball starts at rest and has a constant acceleration. For this problem set the blue ball's acceleration to be $5\mathrm{.}00$ m$/$s$2.$ Note that the simulation may stop slightly after one of the balls reaches the finish line rather than at the instant it reaches the line.

$($a$)$ How far is the second ball from the finish line at the instant the first ball reaches the line?

$($b$)$ Assume the motion continues for both balls until the second ball reaches the finish line. What is the distance between the two balls at that time?
