Eyiafiallajokull is a volcano in Iceland. During a recent eruption the volcano spewed out copious amounts of ash. One small piece of ash was ejected from the volcano with an initial velocity of 368ft/sec. The 2 height H, in feet, of our ash projectile is given by the equation: H=- 16 +368+, where t is the time in seconds. The graph of this equation will be parabola. We will assume that the volcano has no height. I.e, H=0 at t=0. 1) When does the ash projectile reach its maximum height? 2) What is its maximum height? 3) When does the ash projectile return to the ground?
