If We Ignore Air Resistance, the Distance D(t) (In Feet) $d ( t ) = 16 t ^ { 2 }$

Multiple Choice

If we ignore air resistance, the distance d(t) (in feet) that an object travels in free fall can be approximated by $d ( t ) = 16 t ^ { 2 }$ , where t is the time in seconds after the object was dropped.
