The equation that models the movement of the object is:
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:
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

Answer:
Part A)
The height of the water level in the rectangular vessel is 2 centimeters.
Part B)
4000 cubic centimeters or 4 liters of water.
Step-by-step explanation:
We are given a cubical vessel that has side lengths of 10cm. The vessel is completely filled with water.
Therefore, the total volume of water in the cubical vessel is:
This volume is poured into a rectangular vessel that has a length of 25cm, breadth of 20cm, and a height of 10cm.
Therefore, if the water level is h centimeters, then the volume of the rectangular vessel is:
Since the cubical vessel has 1000 cubic centimeters of water, this means that when we pour the water from the cubical vessel into the rectangular vessel, the volume of the rectangular vessel will also be 1000 cubic centimeters. Hence:
Therefore:
So, the height of the water level in the rectangular vessel is 2 centimeters.
To find how how much more water is needed to completely fill the rectangular vessel, we can find the maximum volume of the rectangular vessel and then subtract the volume already in there (1000 cubic centimeters) from the maximum volume.
The maximum value of the rectangular vessel is given by :
Since we already have 1000 cubic centimeters of water in the vessel, this means that in order to fill the rectangular vessel, we will need an additional:
Sincer 1000 cubic centimeters is 1 liter, this means that we will need four more liters of water in order to fill the rectangular vessel.
