The general formula is:

-- (A)
Where g = 9.8 m/s/s

= 0

= 100
a)
Time=t=3s.
Plug-in the values in (A)
y = 100 -(1/2*9.8*3*3)
y = 100-44.1 = 55.9m
Height of the ball exactly after 3 seconds = 55.9m.
b)
At ground, y=0; Plug-in values in (A):
A=> 0 = 100 - (1/2* 9.8 * [tex]t_{2}[/text])
Therefore t = + 4.52 s and - 4.52 seconds.
As t cannot be negative, therefore:
Time when ball hits the ground =
4.52s
-i

Step-by-step explanation:
Answer:
8 square units
Step-by-step explanation:
Area of a rectangle= lenght x width
locating the four points on a Cartesian plane
lenght = BC= AD = (0,4)->(4,4) = 4units
width = AB = CD = (0,2)-> (0,4) = 2units
Area of rectangle = 4units x 2units = 8 square units
