Question 1136274: 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 336 ft/sec.The height H, in feet, of our ash projectile is given by the equation: H=-16t^2+336t, 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. When does the ash projectile reach its maximum height? What is its maximum height? When does the ash projectile return to the ground? thank you for any help!

There is a group of lessons on this subject in this site.  They are

    - Problem on a projectile moving vertically up and down
    - Problem on an arrow shot vertically upward
    - Problem on a ball thrown vertically up from the top of a tower
    - Problem on a toy rocket launched vertically up from a tall platform

Most of all I'd want you read these lessons - after that you will be able to solve your problem on your own.

Consider these lessons as your textbook,  handbook,  tutorials and  (free of charge)  home teacher.
Read them attentively and learn how to solve this type of problems once and for all.
