Answer 1

Answer:

B

Step-by-step explanation:

h(t)=-4.9t^2+ v_0t+h_0

v_0 represents initial velocity

h_0 represents initial height

we use -4.9 for the coefficient of t^2 because we dealing with meters and seconds

(If it was feet and seconds it would have been -16 instead of -4.9)

Anyways v_0 is 15m/s (We will just put 15 to make it look less complicated)

and from the ground means the initial height was h_0=0

So the answer is B.
