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 the initial velocity of 368 ft/sec. The height in H, in feet, of our ash projectile is given by the equation : H = -16t^2 + 368t, where t is time, in seconds.

The graph for this equation will be parabola. We will assume the volcano has no height (i.e. H = 0, t = 0).

1. When does the ash projectile reach the maximum height?

2. What is the Maximum height?

3. When does the ash projectile return to the ground?
