 Eyjafjallajokull 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 368 ft/sec.The height H, in feet, of our ash projectile is given by the equation: H=-16t^2+368t, where t is the time, in seconds. The graph of this equation will be a parabola. We will assume that the volcano has no height. i.e H=0 at t=0. (Question 1.) When does the ash projectile reach its maximum height? (Question 2) What is its maximum height? (Question 3)When does the ash projectile return to the ground?
