Question

If an object is dropped from a height of 200 feet, the function h(t)=-16t^2+200 gives the height of the object after t seconds. Approximately, when will the object hit the ground? (1 point)

Answer 1

just solve for h=0.

-16t^2 + 200 = 0
16t^2 = 200
t^2 = 25/2
. . .

Answer 2

The quadratic formula would also work here, right?

Answer 3

C. 3.54 seconds
