The equation describes the motion of an object thrown upward into the air. In the equation, g is the acceleration due to gravity (9.8m/s²), t is the time elapsed since the object was thrown upward, ν₀ is the initial speed of the object, h₀ is the initial height from which the object was thrown, and h is the height of the object above the ground t seconds after the object was thrown.

How long will it take the object to hit the ground, to the nearest second? (Height of the object is zero when the object hits the ground.)
A) 7
B) 8
C) 9
D) 10
