An object is launched upward
from 62.5 meters above ground level with an
initial velocity of 12 meters per second. the
gravitational pull of the earth is about 4.9
meters per second squared. how long will the
object take to hit the ground?

Check the picture below.  The picture is using feet, but is pretty much the same trajectory for meters.

so the object hits the ground when y = 0, thus

we can't use -2.55, since it's seconds and can't be negative, so t = 5 seconds later.

definition: a circle is the  set of all points in a plane that are equidistant  from a given  point  called the center of the circle. we use the symbol ⊙ to represent a circle. the a line segment from the center of the circle to  any point  on the circle is a radius of the circle.
