A pelican flying in the air over water drops a fish from the height of 30 feet. The distance of the fish from the water can be measured by the function f(t)=-16t^2+30, where is the time in t seconds. A seagull is flying below the pelican when the fish falls. If the seagull flies along a path represented by s(t)=-8t+15, will the seagull be able to catch the fish before the fish hits the water? Justify your answer. If so, find the time it is caught and the distance above the water at that time.
