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 ininitial velocity of 368 ft/sec.
The height H, in feet, of our ash projectile is given by the equation:
H = -16ft^2 + 368t,
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.
When does the ash projectile read its maximum height?
What is its maximum height?
When does the ash projectile return to the ground?
