Ja is a volcano in Iceland. During a recent eruption, the volcano spewed out copious amounts of ash. One small piece of ash was ejected out of 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

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?

Explain how you got the answer and show steps. Thank You :)
