Graham, an alien from another planet, shoots an arrow straight into the air 2.4 meters from
the ground at 36 meters per second. According to the laws of physics on his planet, the
gravity is around 2.78 meters per second squared. The height of the arrow (in meters) is
represented by the equation p = -2.78t2 + 36t + 2.4, where t is the time in seconds)
after the arrow is launched.
How long does it take the arrow to hit the ground?
