An object was launched from the top of a hill with an upward vertical velocity of 80 feet per second. The height of the object can be
modeled by the function h(t) = -16t² + 80t +200, where t represents the number of seconds after the launch. Assume the object landed on the ground at sea level. Find the answer using technology.
__ seconds after its launch, the object fell to the ground at sea level.
