Help plz Two ships are sailing in the fog and are being monitored at ten-second intervals by R.J. Sampson. As they enter his rada screen at 6:00 AM, the Minnow is 1000 meters above the lower left corner of the screen (which will be referred to as the Origin). The Lollipop is 8000 meters directly to the right of the origin After ten seconds, the Minnow is 40 meters east and 10 meters north of its original position After ten seconds, the Lollipop is 30 meters west and 20 meters north of its original position You may assume that the two ships maintain their courses and speed throughout the problem. Do the ships collide?
