A rock is dropped off a cliff that is 18 meters high into a lake below. (Assume there is no air resistance.) The formula for the height of an object dropped is h(t)= 1/2at^2 +s where the gravitational constant, a, is -9.8 meters per second squared, s, is the initial height, and h(t) is the height in meters modeled as a function of time, t. Which of the following are true select all that apply.
The equation for the situation is h(t)= 4.9t^2 + 18.
The equation for the situation is h(t)= -4.9t^2 + 18.
