A. Point A is the coordinate (0,10). (True)
C. Point A represents the initial height of the rock. (True)
E. The equation for the situation is h(t)=4.9t^2+10. (True)
H. The rock hits the surface of the water after 1 5/7 seconds. (True)
A rock is dropped off a cliff that is 10 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 statements are true about the situation and its graph?
Select all that apply.
A. Point A is the coordinate (0,10).
B. Point B is the coordinate (10,0).
C. Point A represents the initial height of the rock.
D. Point B represents the initial height of the rock.
E. The equation for the situation is h(t)=4.9t^2+10
.
F. The equation for the situation is h(t)=−4.9t^2+10
.
G. The rock hits the surface of the water after 1 3/7 seconds
H. The rock hits the surface of the water after 1 5/7 seconds.
