Eyjafjallajokull is a volcano in Iceland. During a new discharge, the volcano spewed out munificent amounts of ash. One slender fraction of ash was ejected from the volcano after a while an primal fleetness of 336 ft/sec. The climax H, in feet, of the ash missile is ardent by the equation: H = - 16tsqual + 336t where t is the opportunity in second.

The graph of this equation procure be a parabola. We procure pretend that the volcano has no climax. H = 0 at t = 0.

When does the ash missile penetrate its consummation climax?

What is it's consummation climax? When does the ash missile reappear to the reason?
