A speedboat traveling at a constant velocity of 20 m/s passes a police boat at rest. The police boat decides that this is much too fast and starts his boat 8 seconds
after the speedboat passes. The police boat accelerates at 2.3 m/s2 for 10 s, then
travels at a constant velocity. When and where does the cop catch the speedboat?
