Eyjafjallajokull is a volcano in Iceland
During the recent eruption, the volcano spewed out copious amount of ash.
One small piece of ash was ejected from the volcano with the initial velocity of 368 ft/sec.
The height (H) , in feet of our ash projectile is givnin by the epuation H= 16T^2 (squared) +368
Where t is the time in seconds
the volcano has no height H=0 and 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 reach the ground?
