according to this Your community is hosting a Crab Festival. As part of the event, there is a contest with prizes for teams that contribute the biggest harvest of freshly caught crabs to the Festival dinner. Teams must deliver their catch by 1030 on the day of the Festival. You form a team with two friends. At 1730 the evening before the festival, your team loads a canoe with your crab trap. You paddle out to a point just off the local beach where you toss the trap into the water. As the trap does down...down...down, the rope feeds out of the canoe until it tugs the buoy tied to the end. The trap pulled the buoy over the gunnel of the canoe and then it too went down. The rope was too short! You could see the buoy floating about 1 metre below the surface of the water, too far down for you to safely reach it to pull it back up. One of your friends observes that the tide is quite high. You make a plan to return to retrieve the trap once the tide is lower. Answer the questions in the…
