A pelican flying in the air over water drops a crab from a height of 30 feet. The distance the crab is from the water as it falls can be represented by the relation
h = - 16t2 + 30, where t is time in seconds. To catch the crab as it falls, a gull flies
along a path represented by g = -8t + 15. Can the gull catch the crab before it
hits the water? Justify your answer with calculations.
