Question 817577: Bob throws a lip gloss from one end of the room to a garbage can at the other. The lip gloss follows a path described by H=-4.9t^2+7.2t+0.5, where H is height in meters and T is time in seconds. The ceiling is only 3m high, will the lip gloss make it to the garbage can, hit the ceiling, or a person.

H=3.1449, t=0.734694
it will hit the ceiling
focus | (3.09388, 0.734694)
vertex | (3.1449, 0.734694)
semi-axis length | 0.0510204
focal parameter | 0.102041
eccentricity | 1
directrix | H = 3.19592
