ikadub [295]
The equation that models the movement of the object is:
 h (t) = (1/2) * (a) * (t ^ 2) + v0 * t + h0

 Where,
 t: time
 a: acceleration due to gravity
 v0: initial speed
 h0: initial height
 Suppose that the object falls with zero initial velocity and from a height of 38 feet.
 The equation that models the problem is:
 h (t) = -16t ^ 2 + 38

 Answer:
 
If an object is dropped from a height of 38 feet, the function h (t) = -16t2 + 38 gives the height of the object after seconds
