HeLLPP! Sean and Mason run out of gas while fishing from their boat in the bay. They set off an emergency flare with an initial velocity of 35 meters per second. The height of the flare in meters can be modeled by h(t)=−5t2 + 35t, where t represents the number of seconds after the launch. How long will it take the flare to get to 30 meters?
Remember to only enter a number. Also, you will get two answers--I want to know when it will first get to 30 meters.
